Answer: 0.025 moles of nitrogen gas are there in the sample.

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 1.03 atm

V = Volume of gas = 568 ml = 0.568 L   (1L=1000ml)

n = number of moles  = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]279K[/tex]

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{1.03atm\times 0.568L}{0.0821L atm/K mol\times 279K}=0.025moles[/tex]

0.025 moles of nitrogen gas are there in the sample.
