A Chemistry question (I always pick best answer)?

Question

What is the mass, in grams, of each of the following?

1. 44.1 mol Xe

2. 1.5 mol W

I'm stuck on this part of the question. Any help would be appreciated!!

Answer 1

44.1 mol Xe *(131.29g/mol)=5789g Xe

1.5 g W *(183.84g/mol)=275.76 g W

Use the atomic mas for the conversions

Answer 2

The gram-molecular weight of Xe is 131.29 grams / mole. Thus, 44.1 moles of xenon has mass 5790 grams.

The gram-molecular weight of W is 183.84 grams /mole. Thus, 1.5 moles of tungsten has mass 276 grams.

Answer 3

1...Moles x Mol.mass = Mass.

Mol.mass Xe = 131g/mol. (From the Periodic Table).

131g/mol. x 44.1mol. = 5,777g.

2...W mol.mass = 184g/mol. (From the Periodic Table).

184g/mol. x 1.5mol. = 276g.
