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

Solution 30P

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

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

(b) 0.581 mol Ba = The molar mass of Ba is 137.32 g/mol

Thus the mass in gram...
