Answer 2

There are 0.236 moles in 13.8 g of sodium chloride

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:

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

$\text{Number of moles}=\frac{13.8g}{58.5g/mol}=0.236moles$

Thus there are 0.236 moles in 13.8g of sodium chloride
