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.

Step-by-step 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 * V_1 = M_2 * V_2`

Substitute the values into above formula as follows.

`M_1 * V_1 = M_2 * V_2\\10 M * 44 mL = M_2 * 176 mL\\M_2 = (10 M * 44 mL)/(176 mL)\\= 2.5 M`

Hence, molarity of the solution is 2.5 M.
