Question

Number of moles present in 200ml of 0.1N H2SO4?

Answer 1

Answer:

Molarity = (number of moles of solute / volume of solution in liters)

Here number of moles = ( given mass of solute / molar mass )

whereas Normality = ( Number of gram equivalent / volume of solution in liter )

where gram equivalent = ( mass of solute / equivalent mass )

Consider an example of H2SO4 whose molar mass = 98 g per mole

Consider a Solution containing 0.98 g of sulphuric acid in 100 mL.

Volume = 100 ml = 0.1 .

therefore no.of moles present in it is 6.083*10 to the power 13*200=567.7538gm/cm3.
