Answer 2

Explanation:

$mass\% = \frac{mass \: of \: solute \: }{mass \: of \: solution} \times 100 \\ \\ mass \: of \: solute(X) = \frac{mass\% \times mass \: of \: solution}{100} \\ = \frac{ \frac{6.24}{100} \times \frac{250}{1000} }{100} \\ \\ = \frac{156.25}{100 \times 100 \times 100} \\ \\ = 1.56 \times {10}^{ - 4} kg \\ \\ \red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
