The accuracy of an instrument was tested by conducting a Reference Standard Material (RSM) experiment. A liquid RSM was prepared by dissolving X mg of phosphate (PO4) in a water sample. At the end of the experiment, the concentration of PO4 in the liquid RSM and the original water sample was recorded as 0.86 mg and 0.48 mg, respectively. The accuracy of the test was then determined as 88%. Calculate X, the amount of PO4 used

The present average concentration (mass percent) of magnesium ions in seawater is 0.13%. A chemistry textbook estimates that if 1.00 × 108 tons Mg were taken out of the sea each year, it would take one million years for the Mg concentration to drop to 0.12%. Do sufficient calculations to either verify or refute this statement. Assume that Earth is a sphere with a diameter of 8000 mi, 67% of which is covered by oceans to a depth of 1 mi, and that no Mg is washed back into the oceans at any time.
A student determined fluoride in a toothpaste sample using ion chromatography. A toothpaste sample of mass 0.100 g was dissolved in type I water and then quantitatively filtered through a Whatman #1 filter paper into a clean 100 ml volumetric flask. The flask was then made up to volume with type I water and mixed thoroughly.A portion of the solution was filtered through a 0.45 um filter into a sample vial for analysis. Analysis of the sample gave a fluoride concentration of 1.60 mg/l Calculate the % w/w fluoride in the original toothpaste sample. (Give your answer to 3 decimal places please)
Suppose that in a gravimetric analysis, you forget to dry the filter crucibles before collecting precipitate. After filtering the product, you dry the product and crucible thoroughly before weighing them. Is the apparent mass of product always high or always low? Is the error in mass systematic or random?
The three sets of units for expressing density (or concentration, as in “mass of solute per unit volume of solvent”) below are equivalent: kg⁄L = g⁄mL =g cm! ⁄a) Using dimensional analysis, show that the above expression is true.b) What is 1.0 kg⁄L = 1.0 g⁄mL = 1.0 g cm! ⁄ expressed in SI base units?
As part of the aspirin synthesis lab the orgo students also had to perform the following calculation to demonstrate their knowledge. Are you able to help them work this out? Saponification is a process in which soap is produced from the chemical reaction between animal fat (triglycerides) and a strong base such as KOH. An example of such balanced chemical reaction is shown here: C51H98O6 + 3KOH → C3H5(OH)3 + 3C16H31O2K (Triglyceride) (Soap) if during the saponification reaction 231.5 g of C51H98O6 is mixed with 231.5 g of KOH and 160 g of soap is produced. Calculate the theoretical yield of soap C16H31O2K and indicate who is the limiting reactant. (Provide your answer to 2 decimal places) Calculate the percent yield for this reaction (Provide your answer to 1 decimal place) *Show ALL steps and mathematical equations involved in your calculations to help the orgo students.

I submitted these responses and they were incorrect. Are there any other suggestions?
1. Explain both precision and accuracy as they pertain to chemical measurements. 2. Why would you use the method of standard addition to calibrate a measurement instead of a calibration curve?
A student failed to carry out all of the procedural steps when doing this experiment. Would the following procedural variations result in an experimentally determined %percent copper in brass? Would it be too low, too high or unaffected? Briefly justify your answer. a) the student did not use a dry beaker when obtaining the stock solution b) the student used a wet cuvette when determining the concentration of solution of unknown brass. c) the student used the wrong wavelength, 430nm, during the measurement of the absorbance of unknown brass solution
An impure sample of 0.1002 g benzoic acid underwent purification by recrystallization. A mass of 0.0542 g of white solid benzoic acid was obtained. Calculate the % purity of the initial sample. Show calculations and report the result with correct number of significant figures. Hi there please answer all parts clearly and concisely with legible hand writting, thank you!
I am trying to ascertain the density of 0.9-M HCl. The book provides a density of 1.0-M HCl as 1.016g/mL. I know the Molecular Weight aka Molar Mass is 36.46g/mol I also know that the equation to calculate the density in this instand is: Density=(Molarity x Molecular Weight)/WeightI have found examples online, and one answer provided here that shows the Density of 0.9-M HCl is 0.9115g/mL. That answer was arrived at as follows:Density = (0.9M x 36.46g/mol)/36 = 32.814/36 = 0.9115g/mL My problem is that I don't understand where the 36 came from for "weight", and I need to be able to show all unit measurements for each step. So my issue has 2 parts: 1) How was the Weight value determined to be 36 (I need to see the formula)2) Where in the step-by-step process is mL in there so that after all cancellations/conversions are completed, the only remaining units are g/mL to show how 0.9115g/mL was arrived at.
A group of students is doing an analysis of copper in a 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. Explain the type of error they are incurring in their experiment.
A volumetric calcium analysis on triplicate samples of the blood serum of a patient believed to be suffering from a hyperparathyroid condition produced the following data: mmol Ca/L = 3.55, 3.65, 3.14. What is the 95% confidence interval for the mean of the data, assuming(a) No prior information about the precision of the analysis?(b) s → σ = 0.056 mmol Ca/L?
