Answer:
723 torr
Step-by-step explanation:
Using the formula;
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (torr)
V1 = initial volume (Litres)
T1 = initial temperature (°C)
P2 = final pressure (torr)
V2 = final volume (L)
T2 = final temperature (°C)
Based on the information provided in this question, V1 = 4.40L, P1 = 555 torr, T1 = 33.0 °C + 273 = 306K, V2 = 3.50 L, P2 = ?, T2 = 44.0 °C + 273 = 317K.
Using the formula above:
555 × 4.4/306 = P2 × 3.5/317
2442/306 = 3.5P2/317
Cross multiply;
2442 × 317 = 306 × 3.5P2
774114 = 1071 P2
P2 = 774114 ÷ 1071
P2 = 722.79
P2 = 723 Torr
