Question

calculate the mass of nitrogen 2L under normal conditions​

Answer 1

Explanation:

NTP stands for Normal Temperature and Pressure at NTP

Temperature is 293 K

Pressure is 1 atm

PV=nRT

n=RT/PV

n=

0.08206 L atm/mol×293 K

1atm×2L

=0.083 mol

Weight of N

2

= No. of moles × molar mass of N

2

=0.083×28=2.33 g
