  • A sample of N2O gas has a density of 2.95 g/L at 298 K. What must be the pressure of the gas?

[tex]\huge\fcolorbox{aqua}{lime}{Answer}[/tex]

  • P = 1203 mm Hg

[tex]\huge{\underline{\underline{\boxed{\sf{\purple{Explanation}}}}}}[/tex]

#Given: -

  • p = 2.85 g/L

  • T = 298 K

# Solution :-

According to ideal gas equation -

➡PV = nRT

➡PV = (W/M)RT

➡PM = (W/V)RT

➡PM = PRT

➡P = pRT/M

➡P = 2.85 × 0.082 x 298 / 44

➡P = 1.583 atm

➡P = 1.583 × 760

➡P = 1203 mm Hg

  • Therefore, pressure of the gas. must be1203 mm of Hg.

Hope this helps you:)
