Determine the volume of nitrogen gas at a pressure of 3.00 atm if it had a volume of 400.0 mL at STP.
(P1V1/T1) = (P2V2/T2)
Remember T must be in kelvin.
To determine the volume of nitrogen gas at a pressure of 3.00 atm, given that it had a volume of 400.0 mL at standard temperature and pressure (STP), we can use the combined gas law, which states:
(P₁ * V₁) / (T₁) = (P₂ * V₂) / (T₂)
where:
P₁ and V₁ are the initial pressure and volume (STP in this case)
P₂ and V₂ are the final pressure and volume (what we want to determine)
T₁ and T₂ are the initial and final temperatures
At STP, the pressure is 1.00 atm, the volume is 22.4 L, and the temperature is 273 K (0 degrees Celsius).
Plugging in the values we have:
(1.00 atm * 22.4 L) / (273 K) = (3.00 atm * V₂) / (T₂)
Simplifying the equation, we get:
22.4 / 273 = 3.00 atm / (T₂ / V₂)
Now, rearranging the equation to solve for V₂:
V₂ = (22.4 * 3.00 atm * T₂) / (273)
Since the temperature is not specified, we cannot determine the exact volume of nitrogen gas at 3.00 atm. The volume depends on the temperature at which the gas is present.
To calculate the volume of nitrogen gas at 3.00 atm, we need to know the temperature.
