Problem 48P

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

Step-by-Step Solution:
Step 1 of 3

Solution 48P

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

  1. Determine how many moles are given in the problem.
  2. Calculate the molar mass of the substance.
  3. 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 = 34.265g

(c)  1.29 mmol carbon disulfide

The molecular weight of a compound may be given as 100 g/mol or 100 mg/mmol

Molar mass of CS2 is 76.139g/mol = 76139 mg/mmol

Thus the mass in mg = 1.29 76139 = 98219.31mg

(d)  1.89 kmol sulfur trioxide

The molar mass of SO3 = 80.066g/mol = 0.080066kg/kmol

Thus the mass of SO3 = 1.89 kmol0.080066kg/kmol = 0.1513kg
