Question

Find the number of moles of argon in 364g of argon.

Answer 1

Answer : The number of moles of argon in 364 g of argon is, 9.1 moles

Solution : Given,

Given mass of argon = 364 g

Molar mass of argon = 40 g/mole

Formula used for determining the number of moles :

$\text{Moles of argon}=\frac{\text{Given mass of argon}}{\text{Molar mass of argon}}$

Now put all the given values in this formula, we get the number of moles of argon.

$\text{Moles of argon}=\frac{\text{Given mass of argon}}{\text{Molar mass of argon}}=\frac{364g}{40g/mole}=9.1g$

Therefore, the number of moles of argon in 364 g of argon is, 9.1 moles
