What is the density (in g/L) of argon at 419 K and under 1 356 atm of pressure?

Question

What is the density (in g/L) of argon at 419 K and under 1 356 atm of pressure? What is the molar mass of a gas which occupies 36.6 L at 379 K under 1 684 atm of pressure and has a mass of 20 9 grams? What is the pressure (in atm) of 25.1 g of oxygen which occupies 32 2 L at 417 K? What is the temperature (in K) of 25 9 g of carbon monoxide which occupies 31 L at 751 torr? What is the volume (in L) of 32.5 g of carbon dioxide a! 442 K and 721 torr? What mass (in g) of carton dox.de occupies a 33.9 L container at 312 K under 0 893 atm of pressure?

Explanation / Answer

1) pressure = 1.356 atm

temperature = 419 K

PV = n RT

P = d R T / M

1.356 = d x 0.0821 x 419 / 39.95

d = 1.575

density = 1.575 g/L

2)

volume = 36.6 L

pressure = 1.684

temperature = 379 K

P V = n R T

1.684 x 36.6 = n x 0.0821 x 379

n = 1.9808

moles = mass / moalr mass

1.9808 = 20.9 / molar mass

molar mass of unknown = 10.55 g/mol
