Question

For the following chemical reaction, what mass of calcium nitrate in grams will be needed to produce 3.17 mol of sodium nitrate?

$$\mathrm{Na_2CO_3} + \mathrm{Ca(NO_3)_2} \rightarrow \mathrm{CaCO_3} + 2\mathrm{NaNO_3}$$

Answer

$$\begin{array}{l} n(\mathrm{Ca(NO_3)_2}) = \frac{1}{2} \cdot n(\mathrm{NaNO_3}) = 0.5 \cdot 3.17 \text{ mol} = 1.585 \text{ mol} \\ M(\mathrm{Ca(NO_3)_2}) = 164 \text{ g/mol} \\ m(\mathrm{Ca(NO_3)_2}) = n(\mathrm{Ca(NO_3)_2}) \cdot M(\mathrm{Ca(NO_3)_2}) = 1.585 \text{ mol} \cdot 164 \text{ g/mol} = 259.9 \text{ g} \\ \end{array}$$

Answer: 259.9 g
