The molarity of a solution obtained by mixing 800 mL of 0.5 M HCl with 200 mL of 1 M HCI will be

A

0.8 M

B

0.6 M

C

0.4 M

D

0.2 M

Text Solution

Verified by Experts

The correct Answer is:
B
`M_1V_1 + M_2V_2 = M(V_1 + V_2)`
` 0.5 xx 800 + 1 xx 200 = M (800 + 200)`
`M = (400+ 200)/(1000) = 0.6 M`
