Answer #1

solution (f) briren P = 85 kPa a 85x10 Pa T- 30F - 292.039 K R = 659 , MNO, = 46 g/mol kg k 46 ideal Kg/mol PV = URT PM=.ART R = 65 x 46 kg = 65 x 46 ) kg k 1000 mol 1000 molk 46 Kg en PM = PRT P-PM 85x10 pax 1000 mol RT 65 x 46 2 x 272.039K 1000 mol

May be some data misprinted in question...

But the process I did is correct

Thankyou... please upvote it ???
