Which of the following has maximum mass?

Options

A. 0.1 moles of ammonia
B. 1120 cc of carbon dioxide at STP
C. 0.1g atom of carbon
D. `6.02 xx 10^(22)` molecules of `H_(2)` gas

Answer

B

Explanation

0.1 mole of `NH_(3) = 0.1 xx 17 g = 1.7 g`
(B) 1120 cc of `CO_(2)` at STP `rArr (1120)/(22400) xx 44g = 2.2 g`
(C ) 0.1 g atom of `C rArr 0.1 xx 12 g = 1.2 g`
(D) `6 xx 10^(22)` molecules of `H_(2)` gas `rArr` 1 mole of `H_(2) rArr 2g`
