Question

44 mL of H2CrO4 is needed to neutralize 176mL of a 10M solution of Pd(OH)4. What is the molarity of this solution?

Answer 1

Answer: The molarity of this solution is 2.5 M.

Explanation:

Given : $V_1 = 44 mL$,           $V_2 = 176 mL$

$M_1 = 10 M$

Therefore, the value of molarity of the solution is calculated using following formula.

$M_1 \times V_1 = M_2 \times V_2$

Substitute the values into above formula as follows.

$M_1 \times V_1 = M_2 \times V_2\\10 M \times 44 mL = M_2 \times 176 mL\\M_2 = \frac{10 M \times 44 mL}{176 mL}\\= 2.5 M$

Hence, molarity of the solution is 2.5 M.
