Question

Calculate the molality of a solution in which 30ml of 0.5 m m2so4 is diluted to 500ml

Answer 1

Answer:

First of all it is not m2so4. It is H2SO4

Explanation:

According to the question to calculate the answer of the mentioned problem,we have to apply the formula of M1V1=M2V2

Here,

The initial molarity or the M1 is 0.5M.

And the initial volume or the V1 is 30 ml.

And,

The final volume or the V2 is 500 ml.

So the,

Final volume will be,

M1V1=M2V2

0.5×30=M2×500

M2=0.5×30/500.

M2=0.03
