Question

How much mass of sodium acetate is required to make 250 mL of $0.575$ molar aqueous solution?

• A. $11.79g$
• B. $15.38g$
• C. $10.81g$
• D. $25.35g$

Answer 1

Answer: (A)

$11.79g$

Answer 2

(1) : Molar mass of sodium acetate $(CH_{3}COONa)$ = $82.0245g/mol$

Mass of $CH_{3}COONa$requird to make 250 mL of $0.575$M solution =

$\frac{0.575 \times 82.0245 \times 250}{1000} = 11.79g$
