1.	The molarity of a solution obtained by mixing 750 mL of 0.5 M HCl with 250 mL of 2 M HCl will beA. 0.975 MB. 0.875 MC. 1.00 MD. 1.75 M
Answer» Correct Answer - B `M_(1) V_(1) + M_(2) V_(2) = M_(3) (V_(1) + V_(2))` `0.5 xx 750 + 2 xx 250 = M_(3) (750 + 250)` or `375 + 500 = 1000 m_(3)` `M_(3) = 875/1000 = 0.875 M`
