Chandra wants to know how many moles are contained in 150.0 g ccl4 (carbon tetrachloride). what quantity of ccl4 should she use to make this conversion?

number of molecules
molecular mass
molar mass
mole ratio

The right answer is Molar mass

The molar mass of CCL4 is 153.82 g / mol. It is a colorless, very volatile liquid whose vapors are harmful to living beings and dangerous for the ozone layer.

If we want to calculate the number of moles.

n = mass / molar mass = 150 / 153.82 = 0.975mol

the answer is 303.15 or 303
