Respuesta :
The number of moles (n) of O2 will be double if atmospheric pressure was doubled and all other variables stayed the same.
About Ideal gas Law
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.
Explanation:
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.
