Question

How much mass does 8.46 moles of XeF6 gas have in grams?

Answer 1

2075g of XeF₆ is present in 8.46 moles of XeF₆

Explanation:

Given:

XeF₆ is xenon hexafluoride

number of moles of XeF₆ is 8.46

Mass of XeF₆ present, m = ?

We know,

Molecular weight of XeF₆, M is 245.28 g/mol

and

number of moles, n = mass of XeF₆ present / molecular weight of XeF6

$8.46 = \frac{m}{245.28} \\\\m = 2075g$

Therefore, 2075g of XeF₆ is present in 8.46 moles of XeF₆
