Question

Part b please.

Resourcos previous 12 of 17 Part A Calculate the density of oxygen, 02, under each of the following conditions STP 1.00 atm and 20.0 °C Express your answers numerically in grams per liter. Enter the density at STP first and separate your answers by a comma. Hints density at STP, density at 1 atm and 20.0C 1.43, 1.33 g/L Submlt Correct When temperature increases, a gas expands and its density decreases. My Answers Give Up ID Part B To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty :2 28.0 "C and weighed it again. The difference in mass was 5.5g. Identify the gas Express your answer as a chemical formula .7-L bulb, then filed it with the gas at 1.80 atm and Hints

Explanation / Answer

PV = nRT

n = W/M

Weight of the gas = 5.5g

R   = 0.0821L-atm/mole-K

T   = 28+ 273   = 301K

P   = 1.8atm

V = 2.7L

PV = WRT/M

M   = WRT/PV

      = 5.5*0.0821*301/1.8*2.7    = 28g/mole

molar mass of N2 = 28g/mole

That gas is N2 ( nitrogen) >>>>>answer
