Question

Determine the mass of 11 moles of SiF4

Answer 1

Step 1

1 mole of SiF4 = 104.04 g of SiF4

(Atomic masses: Si = 28.08; F = 18.99 both from the periodic table)

----------------------

Step 2

Procedure:

`11\text{ moles SiF4 x \lparen}\frac{104.04\text{ g SiF4}}{1\text{ mole SiF4}})\text{ = 1144.44 g}`

Answer: 1144.44 g SiF4
