Answer:
966.4mL
Step-by-step explanation:
Using the combined gas equation as follows:
P1V1/T1 = P2V2/T2
Where;
P1 = initial pressure
P2 = final pressure
V1 = initial volume
V2 = final volume
T1 = initial temperature (K)
T2 = final temperature (K)
According to this question, the following information were provided:
P1 = 998mmHg
P2 (STP) = 760mmHg
V1 = 806mL
V2 = ?
T1 = 26°C = 26 + 273 = 299K
T2 (STP) = 273K
P1V1/T1 = P2V2/T2
998 × 806/299 = 760 × V2/273
804388/299 = 760V2/273
2690.26 = 760V2/273
760V2 = 2690.26 × 273
760V2 = 734440.98
V2 = 734440.98 ÷ 760
V2 = 966.4mL
