Question

The mass of oxyzen in a 11.2L vessel can hold at 380 torr and 0degrees is​

Answer 1

This kind of phase change--liquid to gas--is called evaporation or vaporization. Water vapor can in turn be cooled to form liquid water. This kind of phase change--from gas to liquid--is referred to as condensation. ... Some gases can be cooled down and changed directly into a solid.

Answer 2

Answer: 8 grams

Explanation:

Pressure of the gas = 380 torr = 0.5 atm    (760 torr = 1atm)

Volume of the gas = 11.2 L

Temperature of the gas = °C = 273 K    (0°C = 273 K)

Value of gas constant in in kilopascals = 0.0821 Latm\K mol

According to the ideal gas equation:'

$PV=nRT$

$n=\frac{PV}{RT}=\frac{0.5\times 11.2L}{0.0821 Latm/K mol\times 273K}=0.25moles$

Moles of oxygen gas $O_2$ = 0.25 moles

Mass of oxyge gas =$moles\times {\text {molar mass}}=0.25\times 32=8grams$

Thus mass of oxygen  in a 11.2L vessel at 380 torr and 0 degree is​ 8 grams.
