What is the mass in grams of 2.35 moles of calcium carbonate, CaCO₃?

Question

Quizplus · Accepted Answer

The molar mass of calcium carbonate (CaCO3) can be calculated by adding the atomic masses of calcium, carbon, and oxygen:

CaCO3 = 1 x (40.08 g/mol) + 1 x (12.01 g/mol) + 3 x (16.00 g/mol) 
CaCO3 = 100.09 g/mol

To find the mass of 2.35 moles of CaCO3, we can use the following formula:

mass = number of moles x molar mass

mass = 2.35 mol x 100.09 g/mol = 235 g

Therefore, the mass of 2.35 moles of CaCO3 is 235 grams.
