Page 3 of 3 Gas Density and Molar Mass 9. The density of a diatomic gas is 1.634 g/L at 1.50 atm and 40.0°C. Calculate the molar mass of the gas, and use the periodic table to identify the gas. (10 pts)

Answer 1

PV=nRT I nc moles) = m mcmdar mass PU= m RT M reorganise above EQuestion m = my Rt , density (d) = mass (m) mass volume (U) n=dRT density = 1.634 g/ R (gas constant) = 0.0821 Leatm - molok TC temperature ink) = 48 c = (hot 22315) = 313.15K pressuren

. pressure =P = 1.50 atm = 313-15K ma Em = C1.6342) Coolestation (313.157 Crisosto) I bouton - it is a 28.0 g diatomic gas 7 x, molar mass is 1 mol 28.0 7 no lad g/mol mass of element - 28.09/mol = 14.0 me"

initsagen has molat mass 14.0067 gowe & Ans): gas olas mass :- 28.0 g/mol gas : cgas).
