The number of moles (n) of O2 will be double if atmospheric pressure was doubled and all other variables stayed the same.
<h3>About Ideal gas Law</h3>
The general gas equation, often known as the ideal gas law, is the equation of state for a fictitious ideal gas. It has a number of limitations, but it provides a decent approximation of the behavior of numerous gases under various circumstances.
<h3>Explanation:</h3>
Applying the law of ideal gas: PV = nRT.
where,
P= pressure of the gas in the atm.
V= volume of the gas in L.
n = no. of moles of the gas in mol.
R = Universal gas constant,
T = temperature of the gas in K.
If V and T are constant and have different values of P and n:
(P₁n₂) = (P₂n₁).
P₂ = 2P₁,
∴ n₂ = (P₂n₁)/(P₁) = (2P₁n₁)/(P₁) = 2n₁.
therefore if we double the pressure then no. of the moles of O2 will be doubled.
