Question

What volume of 10% (w/v) solution of Na2co3, will be required to neutralise 100ml of hcl solution containing 3. 65 g of HCI?
Using M1V1=M2V2 formula
​

Answer 1

That's your answer here...

Answer 2

Answer:

0.38M

Explanation:

We know that,

M1V1 + M2V2 = M3V(1+2) {where M denotes molarity and V denotes volume}

as, sum of number of moles in individual solution is equal to number of moles in the mixture.

0.5(20) + 0.3(30) = M3(20+30)

19/50 = M3

0.38=M3

hence the molarity of the resulting solution is 0.38
