How much mass of sodium acetate is required to make 250$$\,mL$$ of 0.575 molar aqueous solution ?
A.
11.79$$\,g$$
B.
15.38$$\,g$$
C.
10.81$$\,g$$
D.
25.35$$\,g$$
Answer :
11.79$$\,g$$
Solution :
Molar mass of sodium acetate $$\left( {C{H_3}COONa} \right) = 82\,g/mol$$
Mass of $${C{H_3}COONa}$$ required to make $$250\,mL$$ of $$0.575\,M$$ soIution $$ = \frac{{0.575 \times 82 \times 250}}{{1000}} = 11.79\,g$$
