Solution

The correct option is B
5.6

M= $\frac{M_{1} V_{1} - M_{2} V_{2}}{V_{1} + V_{2}}$ = $\frac{(0.5) 1 - (0.5) 2}{3}$ =0.5

For 0.89M = 10 vol

∴0.5 M =5.6 vol

The volume strength of solution formed by mixing 1L of 0.5M H2O2 with 2L 0.5 M H2O2 is

The correct option is B 5.6 M=M1V1−M2V2V1+V2= (0.5)1−(0.5)23=0.5 For 0.89M = 10 vol ∴0.5 M =5.6 vol
