The new volume is 2.4 L
<u><em> calculation</em></u>
The new volume is calculated using Boyle's law formula
That is P₁V₁=P₂V₂
where,
p₁ = 802 torr
V₁ = 12.0 l
P₂ = 4010 torr
V₂=?
make V₂ the subject of the formula by diving both side of equation by P₂
V₂ = P₁V₁/P₂
V₂ is therefore = {(12.0 l × 802 torr) 4010 torr} = 2.4 L
The amount of impurities i guess

This question is incomplete
The completed question is below
Which pair of molecules is expected to have the most different properties?
CO and NO
SO₂ and CH₄
The correct answer is SO₂ and CH₄
Explanation:
All the four substances are gases at room temperature.
Carbon monoxide (CO) and nitric oxide (NO) are both reactive oxides. They are both polar and inorganic also, hence should have some similar properties (based on there origin/composition and polarity).
Sulphur dioxide (SO₂) is polar because it's a bent molecule, methane (CH₄) is non-polar because of the tetrahedral shape of it's molecule. Methane is an organic molecule while sulphur dioxide is an inorganic molecule.
From the above, <u>it can be deduced that SO₂ and CH₄ are expected to have different properties</u>. For example, the polarity of SO₂ makes it dissolve in water to form an acidic solution while methane does not dissolve in water and hence doesn't form an acidic solution.
