Part A:
Calculate the molarity of a solution prepared by dissolving 12.1 g of Na2CrO4 in enough water to produce a solution with a volume of 770. mL . M = ?
Part B:
How many moles of KBr are present in 200. mL of a 0.126 M solution? M = ?
Part C:
How many milliliters of 5.4 M HCl solution are needed to obtain 0.19 mol of HCl? M = ?
Part D:
When the following reaction occurs:
H3PO4(aq)+Ca(OH)2(aq)â
what is the formula for the salt formed?
