Final answer:
To find the volume of the oxygen gas at STP, we can use the ideal gas law equation and rearrange it to solve for the volume at STP. Plugging in the given values, the volume of the oxygen gas at STP is approximately 66.8 cm³.
Step-by-step explanation:
To determine the volume of the oxygen gas at STP, we need to use the ideal gas law equation, which states:
PV = nRT
Where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature in Kelvin.
Since the number of moles and the ideal gas constant are constant, we can solve for the volume at STP by rearranging the equation:
V₂ = (P₁V₁T₂) / (P₂T₁)
Where V₂ is the volume at STP, P₁ and T₁ are the pressure and temperature given, and P₂ and T₂ are the pressure and temperature at STP.
Plugging in the values, we find that the volume of the oxygen gas at STP would be approximately 66.8 cm³.
