The mass of 0.500 mol of (NH_4)_2CO is 32 grams

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar Mass}}$

$0.500=\frac{xg}{64g/mol}$

x=32g

The mass of 0.500 mol of (NH_4)_2CO is 32 grams
