What happens if you add a very small amount of solid salt (NaCl) to each beaker described below? Include a statement comparing the amount of solid eventually found in the beaker with the amount you added: a a beaker containing saturated NaCl solution, b a beaker with unsaturated NaCl solution, c a beaker containing supersaturated NaCl solution. A saturated sodium chloride solution.
Tris(pentatluorophenyl)borane, commonly known by its aeronym BARF, is frequently used to initiate polymerization of ethylene or propylene in the presence of a catalytic transition metal compound. It is composed solely of C, F, and B; it is 42.23% C and 55.66% F by mass. a. What is the empirical formula of BARF? b. A 2.251-g sample of BARF dissolved in 347.0 mL of solution produces a 0.01267-M solution. What is the molecular formula of BARF?
A patient has a “cholesterol count” of 214. Like manyblood-chemistry measurements,this result is measured inunits of milligrams per deciliter (mgdL1). Determine the molar concentration of cholesterol inthis patient’s blood, taking the molar mass of cholesterolto be 386.64gmol1. Estimate the molality of cholesterol in the patient’sblood. If 214 is a typical cholesterol reading among men inthe United States, determine the volume of such bloodrequired to furnish 8.10 g of cholesterol.
Explain why the distinction between solute and solvent is not clear for some solutions.
Silver ions can be found in some of the city water piped into homes. The average concentration of silver ions in city water is 0.028 ppm. (a) How many milligrams of silver ions would you ingest daily if you drank eight glasses (eight oz/glass) of city water daily? (b) How many liters of city water are required to recover 1.00 g of silver chemically?
Q. If we are asked to use the recorded Wright of copper(II)sulfate pentahydrate to calculate the exact concentration of of an experimentally recorded copper II sulfate in volumetric flask, do we multiply the grams of copper II sulfate by the molar mass to get the molarity of the copper? Then, do we use the dilution formula to get the concentration. The recorded mass was 2.493 g for 50ml of copper II sulfate stock solution.
40 ml of a 0.100 M sodium phosphate solution is mixed with 40 ml of a 0.200 M cobalt (II) nitrate solution, generating a fine purple solid. The solid is removed via filtration and the liquid is saved. Given that nitrate compounds are always soluble and phosphate compounds are generally insoluble, what chemical species are present in the precipitate and in the supernatant? Explain your answer.
Part C You need to prepare a 2.30 M � solution of potassium bromide (molar mass of potassium bromide = 119.00 g/molg/mol ), but you only have a 10 mLmL graduated cylinder and a 25 mLmL beaker.
