What do you mean by "w/w"?
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

"w/w" probably means weight/weight (in analogy to V/V)
m=0.44 x60 x 1.343

mass of 60ml solution
= 60 x 1.343
= 80.58g

mass of H2SO4 in solution
= 44.0/100 * 80.58
= 35.5g (3s.f.)
