The molarity of a solution obtained by mixing 750 mL of 0.5 (M) HCl with 250 mL of 2(M) HCI will be:

A

0.875 M

B

1.00 M

C

1.75 M

D

0.975 M

Text Solution

Verified by Experts

The correct Answer is:
A
`M_("final") V_("final") = M_1V_1 + M_2V_2`
`M_("final") = (0.5 xx 750 + 2xx 250)/(1000)`
` = (375 + 500)/(1000) = 0.875 M`
