If you did not heat long enough, so that your sample was not completely anyhydrous, would your formula have too many, or would it have too few, waters of hydration?

What is the molarity of the solution resulting from dissolving 10.0 g of silver nitrate in enough water to give a final volume of 885 mL?

1. Calculate the mass needed to prepare 263.0 mL 0.50 M NaOH.

What is the concentration of a solution of a potassium bromide solution if 12.7 g of KBr are dissolved in enough water to make 423.7 ml of solution?

When (NH4 )2SO4 , and BaCl2 are mixed, a precipitate will form. Which ions should act as reactants in the net ionic equation?

Suppose that a solution prepared by dissolving 0.554 g of MgCl2 in about 30 mL of water is mixed with a solution that contains excess K2CO3 dissolved in about 30 mL of water.   What is the theoretical yield (in grams) of MgCO3 in the precipitation reaction that occurs?

If 40.7 g of CH₃OH (MM = 32.04 g/mol) are added to a 500.0 mL volumetric flask, and water is added to fill the flask, what is the concentration of CH₃OH in the resulting solution?

Suppose 9.33g of nickel(II) chloride is dissolved in 250.mL of a 0.30 M aqueous solution of potassium carbonate. Calculate the final molarity of chloride anion in the solution. You can assume the volume of the solution doesn't change when the nickel(II) chloride is dissolved in it.

Calculate the volume (mL) of 1.0 M metal nitrate solution required to prepare 5.0 g of the COBALT pigment. Again, using the balanced chemical equation you should be able to relate the moles of pigment to the moles of metal nitrate and from that calculate the volume of 1.0 M metal nitrate solution required. Please report your value as XX.X mL (one decimal point and no units).

A chemist prepares a solution of iron(II) bromide (FeBr,) by measuring out 97.1 mg of FeBr, into a 100. mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Br anions in the chemist's solution. Be sure your answer is rounded to 3 significant digits. olo mol x10 Ar
