1.	Find the volume occupied by 34g of NH3 at 27°C and 380mm of Hg pressure. (R= 0.084 L atm K-¹ mol-¹), N= 14.H=1.
Answer» Answer: The ideal GAS equation relating pressure (P), VOLUME (V), and absolute temperature (T) is given as: PV = nRT Where, R is the universal gas constant =8.314Jmol−1K−1 n = NUMBER of moles = 1 T = Standard temperature = 273 K P = Standard pressure = 1 atm =1.013×105Nm−2 ∴V=nRT/P =1×8.314×273/(1.013×105) =0.0224m3 =22.4 litres Hence, the molar volume of a gas at STP is 22.4 litres.

Answer:

The ideal GAS equation relating pressure (P), VOLUME (V), and absolute temperature (T) is given as:

PV = nRT

Where,

R is the universal gas constant =8.314Jmol−1K−1

n = NUMBER of moles = 1

T = Standard temperature = 273 K

P = Standard pressure = 1 atm =1.013×105Nm−2

∴V=nRT/P

=1×8.314×273/(1.013×105)

=0.0224m3

=22.4 litres

Hence, the molar volume of a gas at STP is 22.4 litres.
