Question

what is the molarity of 25 percent by weight H2So4 solution ( d=1.2g/m)

​

Answer 1

Answer:

I don't know the answer

Answer 2

Explanation:

volume of H2SO4= 10ml

Volume of water= 90 ml

Density of solution is 1.2 g/cc

mass of aq solution of H2SO4=volume*density= 1.2*100=120gm

Mass of water is= 90*1=90g

Mass of solute i.e. H2SO4= 120-90 = 30g

molality means number of moles of solute present in 1 kg solvent .

Hence molality= number of mole of solute/wt.of solvent in kg

number of mole of solute=30/98=.306
