Answer:
22.4 liters.
Step-by-step explanation:
The volume occupied by a gas at standard temperature and pressure (STP) can be calculated using the Ideal Gas Law: PV = nRT.
In this equation, P represents the pressure, V represents the volume, n represents the number of moles of gas, R is the universal gas constant (8.31 J/mol*K), and T is the temperature in Kelvin.
At STP, the pressure is 1 atm and the temperature is 0°C (273 K). If we know the number of moles of gas, we can calculate the volume it would occupy at STP.
For 100 grams of oxygen gas, we first need to convert the mass to moles using the molar mass of oxygen (32 g/mol).
So, 100 g / 32 g/mol = 3.125 moles of oxygen.
Then, plugging in the values into the Ideal Gas Law equation:
V = nRT / P
V = (3.125 moles) * (8.31 J/mol*K) * (273 K) / (1 atm)
The volume would be approximately 22 L,
