What volume of a 0.6 M KBr solution is needed to provide 30.5 g of KBr?

0.472 L

Explanation:

Molarity is the moles of solute over the liters of solvent. KBr is the solute.

To find the liters of solvent, first convert grams of KBr to moles of KBr. You then divide moles of KBr by the molarity. Your answer should be 0.427 L.
