<span>At STP 1 mol of an ideal gas has a volume of 22.4 L.
We assume (from the question) that the methane has an ideal behavior.
Hence if 1 mole of an ideal gas ccupies a volume of 22.4 L
Then 0.75 mole occupies X
Hence X * 1 = 0.75 * 22.4
X = 16.8L</span>

Answer:
C
Explanation:
As fertilizer can run off into the reservoir and contaminate it with harmful chemicals
1 mol of Silicon = 28.0855 g (in average)
then
1 mol = 6.022*10^23 atoms
then
28.0855/(6.022*10^23) g/atom
4.66381*10^-23 g per atom
