Question

Which of the following has maximum mass :(1) 0.1 gram atom of carbon(3) 6.02 x 1022 molecules of hydrogen(2) 0.1 mol of ammonia(4) 1120 cc of carbon dioxide at STP​

Answer 1

Answer:

1120 cc of CO2at STP has maximum mass.

Explanation:

Atomic Number of carbon = 12g.

0.1 g atom of C= 0.1 mole =1.2 g

0.1 g atom of C= 0.1 mole =1.2 g0.1 mole of NH3

=1.7g

6.02×10²²molecules of H2

= 0.1 mole =0.1 ×1 =0.1g.

( Hydrogen is a diatomic molecule.)

1120 cc of CO2

at STP = 1120/ 22400 mole = 0.05 mole

= 0.05 × 44 =2.20 g.

Therefore, 1120 cc of CO2

Therefore, 1120 cc of CO2at STP has maximum mass.
