##### 1 Answer

#### Answer:

#### Explanation:

On heating the given mixture of 100g of

**The Equation**

According to this balanced equation 2 moles of solid

Molar mass of

Molar mass of

Molar mass of

By the problem the decrease in mass = initial mass -residual mass= =0.31g

According to the decomposition reaction total 44+18=62g decrease in mass occurs for presence of

So decrease in mass of 0.31 g will occur for the presence of

in the given mixture

So the amount

So percentage of
