How Does Changing Temperature and Pressure Affect Gas Density?

[annalian]

Homework Statement

In temperature 273 kelvin and pressure 1.013*10^5 Pa, the density of nitrogen is 1,25 kg/m3. Find the density of this gas in temperature 330 kelvin and pressure 1.40*10^5 Pa.

T1=273 K; p1=1.013*10^5Pa; d1=1.25 kg/m3

T2=330 K; p2 =1.4*10^5 Pa. d2=?

Homework Equations

p1V1/T1=p2V2/T2
