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

A

`1.00 M `

B

`1.75 M`

C

`0.975`

D

`0.875`

Text Solution

Verified by Experts

The correct Answer is:
D
`M _(1) V _(1) + M _(2) V _(2) = MV`
`M = ( M _(1) V _(1) + M _(2) V _(2))/(V) = ( 0. 5 xx 750 + 2 xx 250)/(1000) = 0. 875 M`
