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
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...
