Question

Commercial hydrochloric acid is 12.1 M. What volume of commercial HCl solution should be used to prepare 250.0 mL of 3.00 M HCl

Answer 1

Given :

Commercial hydrochloric acid is 12.1 M.

To Find :

Volume of commercial HCl solution should be used to prepare 250.0 mL of 3.00 M HCl.

Solution :

We know :

`M_1V_1=M_2V_2\\\\V_1=(M_2V_2)/(M_1)\\\\V_1=(3* 250)/(12.1)\ mL\\\\V_1=61.98\ mL`

Therefore, volume of commercial HCl required is 61.98 mL.

Hence, this is the required solution.
