Answer:
12.3 moles of are produced by reacting 18.4 moles of
.
Explanation:
Balanced reaction:
According to balanced equation:
3 molecules of produce 2 molecules of
So molecules of
produce
molecules of
(
is avogadro number).
We know 1 mol of molecule = number of molecules.
So 3 moles of produce 2 moles of
.
Hence 18.4 moles of produce
moles of
or 12.3 moles of
.
Answer:
The molar mass of the gas is 44 g/mol
Explanation:
It is possible to solve this problem using Graham's law that says: Rates of effusion are inversely dependent on the square of the mass of each gas. That is:
If rate of effusion of nitrogen is Xdistance / 48s and for the unknown gas is X distance / 60s and mass of nitrogen gas is 28g/mol (N₂):
6,61 = √M₂
44g/mol = M₂
<em>The molar mass of the gas is 44 g/mol</em>
