Question

what is the volume
of 17 gram of NH3 gas at STP​

Answer 1

Explanation:

vol. of one mole of any substance at STP=22.4L

molar mass of NH3=14+1*3=17g

moles of NH3=

given gram mass/ molar mass

=17/17=1mole

therefore ,

vol. of 1 mole of NH3 at STP=22.4L

Answer 2

Answer:

Volume of NH3 = 22.4 l

$\mathfrak{\large{\underline{\underline{Explanation:-}}}}$

The molar mas of NH3 is :-

= 14 + 3 × 1

= 17 g

According to Gay Lussac's law every gas has same volume which is equal to its molar mass when the temperature and pressure is constant.

1 mole of ammonia has volume of 22.4 l at S. T. P

1 mole ammonia has weight = 17 g

Therefore,

Volume of ammonia NH3 gas at STP is 22.4 l
