Answer:
851 mmHg
Explanation:
Using pressure law equation as follows:
P1/T1= P2/T2
Where;
P1 = initial pressure (mmHg)
V2 = final pressure (mmHg)
P1 = initial temperature (K)
T2 = final temperature (K)
According to the information provided in this question,
P1 = 760mmHg
P2 = ?
T1 = 20°C = 20 + 273 = 293K
T2 = 55°C = 55 + 273 = 328K
Using P1/T1= P2/T2
760/293 = P2/328
Cross multiply
293 × P2 = 760 × 328
293P2 = 249280
P2 = 249280 ÷ 293
P2 = 850.78
Approximately, P2 = 851 mmHg.
