1. At what temperature 28 g of N2 will occupy a volume of 20 litres

1.	1. At what temperature 28 g of N2 will occupy a volume of 20 litres at 2 atm?(a) 300.0 K(b) 487.2 K(c) 289.6 K(d) 283.8 K
Answer» (b) 486.2kExplanation:PV=nRT or T= NR PV (n= M m ) Here, mass of nitrogen m=28g VOLUME of nitrogen V=20litres Pressure P=2atm ∴T= 28×0.0821 2×20×28 =487.2 K.
