Answer 1

S + O2 → SO2

(a) 5so2 will be

5 x 6.023x10^23 molecules

(b)no.of moles in 320g of SO2 gas wii be

 64       →    1 mole

320      →        x moles

  x = 320/64

x no.of moles will be 5

(c) sodium sulphate Na2SO4

1 mole            →         2(23)+32+4(16)==>142

10 moles will be  →  x grams

x grams will be 1420 grams

hope its a needy one♥
