Question

The number of moles of sulphur dioxide in 32 g of so2 gas is

Answer 1

Answer:

Explanation:

Moles=given wt.÷ molar mass

So, moles of SO2= 32÷64=0.5 moles(answer)

Answer 2

Answer:3.011 × 10^23

Explanation:Molar mass of SO2=32+16×2

=64g/mol

64g of SO2 has moles=6.022 × 10^23

1g SO2 has moles=6.022 × 10^23/64

So

32g SO2 has moles=6.022 × 10^23 ×32/64

=3.011 × 10^23
