Question

49g of H2SO4 is present in 100ml solution having density 1.2g/ml What is the molarity of the solution?

Answer 1

molarity=moles of solute/volume of solution

moles of solute=mass/gram molecular mass

gram molecular mass of H2SO4=2+32+64=98g

moles of H2SO4,in solution=49/98=0.5

volume of solution=.1L

molarity=0.5/.1=5g/L

this,will be the required molarity

{hope it helps you}
