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 moles molecular mass molar mass mole ratio.
The molar mass is the number of grams by which there's exactly one mole of one specific substance. So what you do is divide the grams by the molar mass to obtain the number of moles :).
