Answer
a) 12221.76 g W
b) 79.77 g Ba
c) 8941.5 g Xe
d) 50.24 g S
Work Step by Step
Total mass = $moles \times molar mass$
a) Total mass = moles $\times$ molar mass = 6.64 mole $\times$ 184 g/mole = 12221.76 g W
b) Total mass = moles $\times$ molar mass = 0.581 mole $\times$ 137.3 g/mole = 79.77 g Ba
c) Total mass = moles $\times$ molar mass = 68.1 mole $\times$ 131.3 g/mole = 8941.5 g Xe
d) Total mass = moles $\times$ molar mass = 1.57 mole $\times$ 32 g/mole = 50.24 g S
