Answer 1

Here is your answer

Hints:
1 gram atom=1 mole
22.4 litres of gas=1 mole
1000cc=1 litre

Solution:
1) 1 gram atom of C=1 mole=12 grams
2) 0.1 mole of NH3=17/10=1.7 grams
3) 1120cc of CO2=1120/1000=1.120 lites
=0.5 moles=0.5*(12+16+16)= 0.5*44=2.2grams

ANSWER:
option (1) will have the higher mass.
