I am not completely sure, but I don't believe the earth is getting larger.
Answer:
Volume occupied by oxygen gas at 15 degree centigrade is equal to
centimeter cube
Explanation:
Assuming Pressure is constant.

where T1 and T2 are temperature in Kelvin
Substituting the give values we get-


Volume occupied by oxygen gas at 15 degree centigrade is equal to
centimeter cube
Unit conversion is a multi-step process, in which division or multiplication by a numeral factor is involved.
Density =
(given)
Since,
and

Now, converting
to
:

=
.
Hence, density is
.
