1/2
1/10
1
1/3

Answer 1

1/10 is equal to 5.85 gm NaCl

Answer 2

5.85 g Nacl is equal to $\frac{1}{10}$

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number $6.023\times 10^{23}$ of particles.

To calculate the moles, we use the equation:

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

Given mass = 5.85 g

Molar mass = 58.5 g/mol

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