What is the molarity of a solution if you take 12.0 grams of ca (no3) 2 and mix it with 0.105 l of water?

The molarity of a solution if it tale 12.0 grams of Ca (No3) 2 is calculated as below

molarity = moles/volume in liters

moles = mass/molar mass = 12.0 g / 164 g/mol = 0.073 moles

molarity is therefore = 0.073/0.105 = 0.7 M
