Answer
(a) $2.6\,kg$
(b) $1.0\times10^{2}\,g$
(c) $18\,g$
Work Step by Step
Mass % of NaCl= $\frac{\text{Mass of NaCl}}{\text{Mass of NaCl solution}}\times100\%$
$\implies \text{Mass of NaCl solution}=\frac{\text{Mass of NaCl}}{\text{Mass % of NaCl}}\times100\%$
(a) $\text{Mass of NaCl solution}=\frac{\text{Mass of NaCl}}{\text{Mass % of NaCl}}\times100\%$
$=\frac{1.5\,g}{0.058}\times100=2.6\times10^{3}\,g=2.6\,kg$
(b) $\text{Mass of NaCl solution}=\frac{1.5\,g}{1.46}\times100=1.0\times10^{2}\,g$
(c) $\text{Mass of NaCl solution}=\frac{1.5\,g}{8.44}\times100=18\,g$
