A solution of a salt has density of \( 1.2 g / cc \) and concentration of \( 45 \% \) by mass of the salt. What volume of this solution would contain \( 20 g \) of the salt? |

Answer» Given :
solution : \(\text{percentage by volume}(w/V\%)=(w/w\%)\times{d}\) (w/V%)=45×1.2 (w/V%)=54 We know that , \((w/V\%)=\frac{\text{weight of solute}}{\text{volume of solution}}×100\) \(54\%=\frac{20}{x}\times{100} \\x=37.03\text{ml}\) Volume of solution will be 37.03ml |
