Question

The mass of 89.6 ml of gas at NTP is 0.224g. Calculate the molecular mass of the gas.​

Answer 1

Answer:

Correct answer is

4×6.02×10

23

Explanation:

No. of moles of a gas at NTP= Volume in litres/22.4

So, 89.6 litres of gas= ( 89.6/22.4) moles of gas = 4 moles of gas

No. of molecules= Moles X Avogadro's no = 4 x 6.02 X ( 10^23)
