Question

2 dm' of 4M H2SO4 is mixed with 3 dm3
water. What is the molarity of the final
solution ? [1.6]​

Answer 1

Answer:

1.6

Explanation:

As we know C =n/V

here it is given that C = 4M and V = 2 dm3/ Ltr

so no. of moles, n = 4×2 = 8

and then 3 dm3/Ltr water is added

so mix. volume is 5 dm3. And no of moles will be same,

n= 8

so Conc,C = n/V

C = 8/5 = 1.6
