Question

The no of moles of of gas in 1m3 of volume at NTP is

Answer 1

Answer: 44.6 moles is the right answer

Explanation:

Answer 2

Answer: 41.6 moles

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

According to the ideal gas equation:'

$PV=nRT$

P = Pressure of the gas = 1 atm at NTP

V= Volume of the gas = $1m^3=1000L$

T= Temperature of the gas = 20°C (at NTP) = (20+273)K= 293 K    

R= Gas constant = 0.0821 atmL/K mol

n=  moles of gas= ?

$n=\frac{PV}{RT}=\frac{1\times 1000}{0.0821\times 293}=41.6moles$

Thus the no of moles of gas in $1m^3$ of volume at NTP is 41.6.
