Question

2.5 dm3 of dry nitrogen gas is collected at a temperature of 27 °C and a pressure of 740 mm Hg. Find the volume of gas at STP.

Answer 1

Answer:

5.6l

Explanation:

we know that PV is equal to nrt and also P is equal to Drt÷M in this formula at STP Vino density gas constant and temperature and also pressure by this we can calculate molecular mass by molecular mass we can calculate number of moles and then by pv=nrtby substituting the values of pressure number of moles gassed constant and temperature we can get the volume which is equal to 5.6 litres .

Answer 2

Answer:

Explanation:

Hope this helps!
