Answer 2

The number of moles of NaCl for given amount is $\frac{1}{10}mol$

Explanation:

To calculate the number of moles, we use the equation:

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

We are given:

Given mass of NaCl = 5.85 g

Molar mass of NaCl = 58.5 g/mol

Putting values in above equation, we get:

$\text{Moles of NaCl}=\frac{5.85g}{58.5g/mol}\\\\\text{Moles of NaCl}=\frac{1}{10}mol$
