this is your answers of Your question

Answer 2

Given,

Mass of salt $\[ = 5.30g\]$

Mass of water $\[ = 19.7g\]$

Solution,

Calculate the percent by mass concentration of a solution,

$\[ = \frac{{5.30}}{{19.7}} \times 100\]$

$\[ = 26.9\% \]$

Hence the percent by mass concentration of a solution is $\[ 26.9\% \]$
