Answer:
3.43atm
Explanation:
Using the combined gas law equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
T1 = initial temperature (K)
T2 = final temperature (K)
According to the provided information in this question,
P1 = 1 atm (standard pressure)
P2 = ?
V1 = 63mL
V2 = 20mL
T1 = 273 K (standard temperature)
T2 = 24°C = 273 + 24 = 297K
Using P1V1/T1 = P2V2/T2
1 × 63/273 = P2 × 20/297
63/273 = 20P2/297
Cross multiply
297 × 63 = 273 × 20P2
18711 = 5460P2
P2 = 18711/5460
P2 = 3.426
P2 = 3.43atm
