Question

Calculate the total pressure in a mixture of 1 gram of dioxygen and 4 gram of dihydrogen confined in a vessel of 1 decimeter cube at 27 degree celsius take our as 0.083 bar per decimeter cube kelvin per mall

Answer 1

4706 pascal

PV = nRT

P = pressure : 0.083 bar = 8300pascals

V = Volume (litr)

n = moles R = const (8.3145) T = Kelvin Temp =

n1 = 1/32 ; n2 = 4/2 = 1/2

V1 = V2 = 1(dm)^3 = 1Ltr

T1 = T2 = T = 27+273 = 300K

P = P1+P2 =RT/(n1+n2)

P= 8.3145 * 300/(1/32+1/2)

P = 4706pascal
