Question

what is the volume of 5.60g of O2 at 7.78 atm and 415k?

Answer 1

The volume occupied by oxygen is 0.77 L.

¿What is the volume of a gas?  

The volume of an ideal gas is the three-dimensional space that it occupies, as if it were only in the container. A gas can expand because its molecules can be pulled apart due to low intermolecular forces between them. It can also be compressed and reduced in volume. These two situations indicate the work done by the gas.

The volume of the gas is calculated by the fundamental equation of ideal gases, whose formula is.

P V= n R T

data

V=?

m = 5.60 g

P= 7.78 atm

T= 415 K

R= 0.082 atm L /K mol

1 Calculation of moles

mole oxygen= m/PM

PM O2= 2 *16 g/ mol = 32 g/ mol

mol O2= 0.175 mol

mol= 5.60 g/ 32 g/ mol = 0.175 mole

1. Volume calculation

$V=\frac{0.175 mol *0.082 atm L/K mol * 415 K}{7.78 atm} = 0.77 L$

V= 0.77 L
