Question

What will be the molality of the solution obtained by dissolving 4.9g sulphuric acid in 250g water?​

Answer 1

Answer:

Molar mass of sulphuric acid is 98.07g/mol Therfore 4.9g contains 0.04996 ... What is the molarity of 0.4 normality of H2SO4 solution?

Answer 2

Answer:

Molarity, M=

volume(L)

no. of moles

Volume, V=250mL=0.25L

No. of moles, n= mass/molar mass

Mass = 49 g

Molar mass of H

2

SO

4

= 98 g

n=49/98=0.5

M=0.5/0.250=2M
