Answer 2

Answer:

Solution of the final solution can be found in the following way

Explanation:

We know that,

$M_{1} V_{1}$ + $M_{2} V_{2}$ = $M_{3} V_{3}$ - (1)

Given:

$M_{1}$ = 0.01, $V_{1}$ = 3.5 L, $M_{2}$ = 0.05, $V_{2}$ = 1.5 L

Putting all the above conditions in equation (1), we get,

0.01 × 3.5 + 0.05 × 1.5 = $M_{3}$×(5)

⇒ $M_{3}$ = 0.022
