A student checked the accuracy of two standard top-loading balances by testing them with a standard 5.000-g mass. The results were as follows: Balance 1: 4.99 g, 5.04 g, 5.03 g, 5.01 g Balance 2: 4.97 g, 4.99 g, 4.95 g, 4.96 g Calculate the average values for balances 1 and 2 and calculate the percent error for each. Which balance is more accurate?
Magnesium chloride is an important coagulant used in the preparation of tofu from soy milk. Its solubility in water at 20C is 54.6 g/100 g. At 80C, its solubility is 66.1 g/100 g. A mixture is made up of 16.2 g of magnesium chloride and 38.2 g of water at 20C. (a) Is the mixture homogeneous? If it is, how many more grams of magnesium chloride are required to make a saturated solution? If the mixture is not homogeneous, how many grams of magnesium chloride are undissolved? (b) How many more grams of magnesium chloride are needed to make a saturated solution at 80C?
At 20oC 25.0 ml of concentrated nitric acid solution was found to have a mass of 32.503 g. What is the calculated density of this solution at 20oC? Show your calculation set-up and result using correct significant figures and proper units. Volume of Nitric acid = 25.0 ml Mass of nitric acid = 32.503 g Density = mass of substance Density= Mass of nitric acid volume of substance volume of nitric acid = 32.503g 25 .0mL = 1.30g/mL (3 sig figures) Using the calculated density of the solution from above, what is the mass of 150 ml. of the solution? Again show your solution set-up with correct significant figures and units.
A density bottle test on a sample of dry soil gave the following results:Mass of 50ml density bottle empty (g) = 25.07Mass of 50ml density bottle+20g of dry soil particles (g) = 45.07Mass of 50ml density bottle+20g of dry soil particles, with remainder of space in bottle filled with water (g) = 87.55Mass of 50ml density bottle filled with water only (g) = 75.10Calculate the relative density (specific gravity) of the soil particles. Round your answer to 2 decimal places.
1.) A dense plastic-like shape has a mass of 42.985 g and has a volume of 41.96 mL. What is the density of the substance? 2.) Another plastic-like piece has a mass of 65.389 grams and displaces 53.652 grams of water (measured at 24.6 ⁰C). Is this piece likely to be composed of the same material as the sample in problem 1? Explain using the Claim-Evidence-Reasoning process.

You are asked by the King of Allegesia to determine if the crown he was given for his birthday is pure gold. The density of pure gold is 19.32 g/mL; the density of water is 0.998 g/mL at 20ºC. There is a container when filled to the mark contains 1900.0 mL. When the container is filled with water to the mark, it has a mass of 2499.5 g. The crown is placed in the container and filled to the mark with water and now weighs 15,113.3 g. The crown has a mass of 13,910.0 g. What is the density of the crown? Is the crown pure gold?
A student decided to undertake a balance calibration exercise during a lab session involving burette calibration. He found the apparent weight of calcium carbonate in air to be 100 grams and density to be 1.33g/mL. Assume that the standard steel weight used in the calibration has a density of 8.0g/mL and air has a density of 0.0012g/mL. What would be the true mass of the calcium carbonate sample?
