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

A

0.975 M

B

0.875 M

C

1.00 M

D

1.175 M

Text Solution

Verified by Experts

The correct Answer is:
B
`M_(1)V_(1)+M_(2)V_(2)=M_(3)(V_(1)+V_(2))`
`0.5xx750+2xx250=M_(3)(750+25)`
`375+500=1000M_(3) or M_(3)=(875)/(1000)=0.875M`
