The equations given below relate to the manufacture of sodium carbonate (molecular mass of
`NaCl+NH_(3)+CO_(2)+H_(2)O to NaHCO_(3) +NH_(4)Cl`
Na `CO_(3) = 106).`
`2NaHCO_(3) to Na_(2)CO_(3)+H_(2)O+CO_(2)`
Question a and b are based on the production of 21.2 g of sodium carbonate
a. What is the mass of sodium hydrogen carbonate must be heated to give 21.2 g of sodium carbonate (molecular weight of NaHCO_(3) = 84)

Explanation

To solve the problem of determining the mass of sodium hydrogen carbonate (NaHCO₃) required to produce 21.2 g of sodium carbonate (Na₂CO₃), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reaction**:
We know from the video transcript that the relevant reaction is:
\[
2 \text{NaHCO}_3 \rightarrow \text{Na}_2\text{CO}_3 + \text{H}_2\text{O} + \text{CO}_2
