Question

3. Convert 0.500 mol (NH4)2CO, to grams.

please explain how ​

Answer 1

Answer: 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
