Question

4.9 gram H2SO4 is mixed with water to form 5 litres of aqueous solution.find it's concentration. (molecular weight of H2SO4 is 98gram/mole)

Answer 1

Concentration simply means molarity i.e, no. Of moles of solute dissolved in one litre of the solution

Therefore, 4.9/98 into 1000/5=10

Thus 10 M will be it's concentration. As simple as that!
