Question

find the mole fraction of H2SO4 if 49g of H2SO4 is dissolved in 360 ml of water ​

Answer 1

Answer:

Molar mass of sulphuric acid is 98.07g/mol

Therfore 4.9g contains 0.04996 moles.

0.04996 mol/500ml =( 0.04996 x2) moles per litre = 0.09992 moles per litre

Therefore 4.9g H2SO4 in 500 ml = approx. 0.10M

Answer 2

Answer:

Molar mass of sulphuric acid is 98.07g/mol

Therfore 4.9g contains 0.04996 moles.

0.04996 mol/500ml =( 0.04996 x2) moles per litre = 0.09992 moles per litre

Therefore 4.9g H2SO4 in 500 ml = approx. 0.10M
