Question

20. Calculate the volume occupied by (0) 28 u nitrogen gas (ii) 28 g N, gas at STP.​

Answer 1

Answer:

28 u N 2 gas contains one mole of N2

Explanation:

thatthat is 6.022 into 10 to the power 23 molecules of N2 occupies 22.4 I show one mole of N2 occupies 22.4 by 6.023 into 10 to the power 23 equal to 3.72 to into 10 to the power 23 litre

Answer 2

Explanation:

Given :-

• 28 u nitrogen gas
• 28 g N, gas at STP.

To Find :-

• Calculate the volume occupied

Solution :-

• (1.) 28u =1 mole of N2

Then volume occupied is 22.4L

• 22.4L/6.022×10^23=3.72×10^23.

• ( 2 ) 28g means = 1 mole of N₂ gas

Therefore it will occupy 22.4L at STP.
