A sample of an ideal gas has a volume of 2.34 L at 279 K and 1.10 atm. What is the pressure when the volume is 1.78 L and the temperature is 304 K?

Pressure = 1.6 atm

Explanation:

Use the formula (P_1V_1)/T_1 = (P_2V_2)/T_2, where P_1 is the initial pressure, V_1 is the initial volume, and T_1 is the initial temperature. And V_2\, P_2\, T_2 are the final values (with the variable you're trying to find!)

Substitute the values into the formula.

((1.10atm)(2.34L))/(279K)= ((P_2)(1.78L))/(304K)

(304)(1.10)(2.34) = (P_2)(1.78)(279)

782.5 = 496.6 (P_2)

P_2 = 1.6 atm
