Question

The mass of oxygen that a 11.2 L
vessel can hold at 380 torr and
0°C is
1) 4g 2) 8 g 3) 16 g 4) 32 g​

Answer 1

Answer:

The mass of oxygen in a 11.2L vessel at 380 torr and 0 degree is​ 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 kilo pascals = 0.0821 L atm\K mol

According to the ideal gas equation:'

Moles of oxygen gas  = 0.25 moles

Mass of oxygengas =moles×molar mass=0.25×32=8grams

Answer 2

Explanation:

mass of o2 - molrs x molar mass

.25 x 32

-32
