What is the mass in grams of each elemental sample?

(a) 6.64 mol W

(b) 0.581 mol Ba

(c) 68.1 mol Xe

(d) 1.57 mol S

Step 1 of 4

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) 6.64 mol W = The molar mass of W is 183.84 g/mol.

Thus the mass in gram is = 6.64 mol (183.84 g/mol) = 1220 g W
