Calculate the density of oxygen,
abruzzese [7]

Answer:

density of oxygen = 1.307 g/l

Explanation:

given pressure = 1 atm temperature = 298 k

PM=DRT

where p is pressure M is molecular mass D is density R is gas constant and T is temperature

substituting the values in the equation

1\times 32=D\times 0.0821\times 298

D = 1.307 g/l.
