Question

which of the following has maximum mass?(1)0.1g atom of nitrogen(2) 0.1mol of ammonium(3)6.02×10²³molecules of Helium gas(4)1120cc of Carbon dioxide
Want with explanation
ASAP ​

Answer 1

Answer:

14g N2.........6.022×1023 atom=Na atom

0.1g ........14×0.1/Na gm

0.1 mol NH3.......1.7gm

6.02×10^23 molecules........... 4gm He

22400cc......,.44gm CO2

1120cc........ 44×1120/22400= 2.2 gm CO2

Explanation:

so, 6.02×10^23 molecules of He has maximum mass
