Question

The molarity of a solution obtained by mixing 750ml of 0.5 M HCl with 250ml of 2 M HCl will be? (JEE Main)​

Answer 1

Answer:

... obtained by mixing 750 mL of 0.5 (M) HCl with 250 mL of 2(M) HCl will be. ... molarity of resulting solution of HCl =

tha resultant molar it when two acids or two bases are mixed is given by M = M1V1+M2V2 /

Answer: 0.875Explanation: $M_1V_1+M_2V_2=M_3(V_1+V_2)$where $M_1$= molarity ...

Answer 2

M = 0.75L × 0.5 + 0.25L × 2 / 1 L

= 0.375 + 0.5

= 0.875 Ans.
