Answer 1

Heya!!
_____________-★_★

At first balance the equation

Zn + H2SO4 -----> ZnSO4 + H2

I.e

1 mole Zn gives 1 mole H2

and 1 mole H2 at STP = 22.4L

SO,

FOR 22.4 L H2 we need 1 mole Zn

for , 224/1000( converted ml to L)
we need

(1/22.4) × 224/1000 = 0.01 mole Zn

also, 1 mole Zn = 65g

0.01 mole Zn = 65×0.01 = 0.65g

hope it helps!!
