Question

(b) How many chlorine molecules are there in 1 g of chlorine?​

Answer 1

Explanation:

1 g of chlorine is composed of 1.72\times 10^{22}

molecules.

Given:

Weight of chlorine = 1 g

To find:

Number of molecules = ?

Formula to be used:

Number of molecules =$\frac{Given mass}{Molar mass} \times Avogadro number$

Calculation:

The given substance is Chlorine. For it

Given mass = 1g

Molar mass = 35 g

Avogadro number = $6.022\times10^{23}$

Substituting the given values in the following formula gives:

Number of molecules = $\frac{Given mass}{Molar mass} \times$

Number of molecules = $\frac{1}{35}\times 6.022\times10^{23}$

Number of molecules =$\frac{6.022\times 10^{23}}{35}$

Number of molecules = $0.172\times 10^{23}$

Conclusion:

$1.72\times 10^{22}1.72×10$

molecules are present in 1g of chlorine.
