Determine the mass of each sample.

(a) 1.32 mol carbon tetrafluoride

(b) 0.55 mol magnesium fluoride

(c) 1.29 mmol carbon disulfide

(d) 1.89 kmol sulfur trioxide

Solution 48P

There are three steps to converting moles of a substance to grams:

Determine how many moles are given in the problem.Calculate the molar mass of the substance.Multiply step one by step two.(a) 1.32 mol carbon tetrafluoride

The molar mass of CF4 is 88.0043 g/mol. Thus the mass in gram = 1.32 88.0043 = 116.165g

(b) 0.55 mol magnesium fluoride

The molar mass of MgF2 is 62.3018 g/mol. Thus the mass in gram = 0.55 62.3018...
