Question

< Question 6 of 9 > A 1.35 g sample of an unknown gas at 81 °C and 1.00 atm is stored in a 2.05 L flask. What is the density of the gas? density: g/L What is the molar mass of the gas? molar mass: g/mol

Answer 1

the density and molar mass has been calculated...hope this solution helps...thank you.

We know for a moles of an ideal gas : PV: MRT where, pe pressure = 1:00 atm Ve volume - 2.05 L na co (we quen moss, roar mass) R = 0.082 Latom Kr med Ta 8100 = 354k ( 1 c = 2736) 3 e Now, we know that's Density z mass volume 1.35 g 2.05 i 0.658 ge PV = nRT » PV W RT. , Ms WBT & m = 1.25% 0.082 x 354 2.054 1.00 VY = 39.187 = 19.11 g/not 2.05 80 Density of the gas - 0.658 91 Mah you de yag = 10. 11 а тKM
