Question

The number of atoms and molecules present in 44.8l of nitrogen at NTP.what will be the mass of 22.4L of nitrogen at NTP

Answer 1

Explanation:

Answer

Pressure= 2 atm

temperature= 273K

volume= 44.8cm

3

=44.* litre

so,By PV=nRT

n=

RT

PV

mole=

0.0821×273

2×44.8

so, no of moles= 3.998=4

hence, 4×6.023×10

23

=24.08×10

23
