Question

You have 10.0 L of nitrogen gas at 90°C and 150 kPa. What volume of gas will you have at STP?

A. 21.67 L
B. 33.90 L
C. 11.14 L
D. 17.94 L

Answer 1

To find the volume of gas at STP, use the ideal gas law equation and plug in the given values. The volume of gas at STP is approximately 17.94 L.

Step-by-step explanation:

To find the volume of gas at STP, we can use the ideal gas law equation. Rearranging the equation to solve for volume, we have:

V2 = V1 * (P1 * T2) / (P2 * T1)

Where V1 is the initial volume, P1 is the initial pressure, T1 is the initial temperature, V2 is the final volume at STP, P2 is the standard pressure of 1 atm, and T2 is the standard temperature of 273 K. Plugging in the given values, we have:

V2 = 10.0 L * (150 kPa * 273 K) / (1 atm * 363 K)

V2 ≈ 17.94 L

Therefore, the volume of gas at STP is approximately 17.94 L.
