Answer 2

Explanation:

3.

32g of O2. = 2xNo atoms (No=avagadro no.)

20g " " = (2/32)x20 No=1.25 No atoms

44g of CO2 = 3 x No

1.25 No = ( 4 4 / 3 ) x 1.25 = 18.33g CO2

1.No of moles. = No of nolecules/Avg No

= (6.023×10^20) / (6.023×10^23)

= 10^-3 moles

10^-3 = Wt/ molecular mass

= 44× 10^-3/10^-3

= 44g

2.1g of carbon has more atoms ,as atomic number of carbon is more than H2
