Question

HELP ME FRIENDS PLZZZ

Answer 1

a) 2* Atomic Mass of H+ Atomic Mass of S+4*Atomic Mass of O
2*2+32+4*16
4+32+64
100u

Answer 2

Molecular mass of H2SO4 is
1ux2 + 32u + 16ux4
=2u + 32u + 64u
=98u.




$\: \: \: \: \: \: \: \: no.of \: moles = \frac{given \: mass \: }{molecular \: mass} \\ = > no.of \: moles = \frac{17}{1 \times 2 + 16 \times 2} \\ = > no.of \: moles = \frac{17}{34} = \frac{1}{2}moles.$
