Question

7g of nitrogen occupies a volume of 5litres under certain conditions .under the same conditions one mole of a gas ,having molecular weight 56 occupies a volume of

Answer 1

Answer:

Answer is 20L.

Explanation:

Step 1: To calculate number of moles of N2 (7g.)

Number of moles of N2 = 7/28=0.25 moles

Step 2: To calculate litres occupied by 0.25 moles of N2

We know,

0.25 moles occupy 5L of volume.

 1 mole of gas occupies 50/0.25 = 20L.

Therefore, required answer is 20L of gas is occupied by one mole of gas.
