Question

76. Which one of the following statements is true?
a) Mass of 0.5 mole of N, gas > Mass of 0.5 mole of N-atoms
b; Mass of 0.5 mole of N, gas = Mass of 0.5 mole of N-atoms
e) Mass of 0 5 mole of N, gas <Mass of 0.5 mole of N-atoms
d) Mass of 0.5 mole of N, gas = Mass of 0.5 mole of 0,-atoms​

Answer 1

Answer:

a) gas>atoms

Explanation:

0.5 mole of N2 means 3.011×10^23 molecules

but each molecule has 2 atoms of N

Therefore no. of N atoms 2×(3.011×10^23)=6.022×10^23 atoms

0.5 mole of N atoms is 3.011×10^23 atoms

Clearly, N2 gas weighs more
