The molar mass of C3H8 is 44.11g, so 44.11g/22.4L = 1.96g/L I think this is the answer, I'm not sure but I hope this is make you easier :)
The density of propane gas is 2,0098 kg/m3 at 0 0C and 1 013 mbar.
The volume is 1,622 L.
The density of hydrogen sulfide is 1.363 g/cm3.
i dont now
2.892 kg/m3

Argon has a density of 1.78 g/L at STP. One gallon =3.785 liters. So 1.78 g * 3.785 = 6.74 grams per gallon.
The estimated value of the density of francium at STP is 1,87 g/cm3.
no
The density of hydrogen sulfide is 1.363 g/cm3.
The Density of Neon at STP is: a 0.89994 mg/cm-3.
The predicted density of rutherfordium is 23,2 g/cm3.
