Task:

10 gms of sodium carbonate is dissolved in 36 ml of water. Volume percentage of solution is?

Answer:

$$w = \frac {m \left(N a _ {2} C O _ {3}\right)}{m \left(N a _ {2} C O _ {3}\right) + m \left(H _ {2} O\right)} \cdot 100 \%$$ $$M \left(H _ {2} O\right) = V \left(H _ {2} O\right)$$ $$w \left(N a _ {2} C O _ {3}\right) = \frac {10}{10 + 36} \cdot 100 \% = 21 \%$$
