Question

Helium is a colourless, odorless used in bolloons. Calculate . the pressure Cin atm) exerted by 1.82 mous of gas in a steel vessel of volume 5.43 L at L 69.58°C​

Answer 1

Answer:

9.59 atm

Explanation:

Use ideal gas law    PV = n RT

 V = 5.34 L    n = 1.82 mole   T = ( 69.58+ 273.15) = 342.73 K

         R = .082057  L-Atm/(K - mole)

P  = n RT / V = 9.59 Atm
