Question

5 moles of oxygen gas is equal to how many grams?

Answer 1

160 g

Step-by-step explanation:

1 mole of oxygen atom = 16 g

Number of moles of oxygen given = 5 mole

Molecular weight of oxygen molecule = 32 g/ mole

Weight of oxygen in gram = 5 mol x 32 g/mol= 160 g

Therefore, 160 g of oxygen is present in 5 moles.
