Concentration of 4 M aq. H2SO4, solution in molality is (density of H2SO4 soln. 1.992 gram/mol)?
[ans:- 2.5m] please explain...
​

Answer 1

Answer:

Molarity=

Molarity= Molar mass×100

Molarity= Molar mass×100% by mass×1000×density

Molarity= Molar mass×100% by mass×1000×density

Molarity= Molar mass×100% by mass×1000×density

Molarity= Molar mass×100% by mass×1000×density =

Molarity= Molar mass×100% by mass×1000×density = 98×100

Molarity= Molar mass×100% by mass×1000×density = 98×10040×1000×1.2

Molarity= Molar mass×100% by mass×1000×density = 98×10040×1000×1.2

Molarity= Molar mass×100% by mass×1000×density = 98×10040×1000×1.2

Molarity= Molar mass×100% by mass×1000×density = 98×10040×1000×1.2 =4.89M≈4.9M
