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?

1 answer:

8 0

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
