Approximately
, assuming that this gas is an ideal gas.
Explanation:
Look up the standard room temperature and pressure:
and
.
The question states that the volume of this gas is
.
Convert the unit of all three measures to standard units:
Look up the ideal gas constant in the corresponding units:
.
Let
denote the number of moles of this gas in that
. By the ideal gas law, if this gas is an ideal gas, then the following equation would hold:
Rearrange this equation and solve for
:
In other words, there is approximately
of this gas in that
.
