Answer:
322.5mL
Explanation:
According to Charles's law, which state that at constant pressure the volume of fixed mass of a gas is proportional directly to it's temperature.
This can be expressed as
V1/ T1 = V2 / T2
Where
V1= initial volume= 693 mL
V2= final volume
T2= final temperature=( –125°C + 273)= 148K
T1= initial temperature= (45°C+ 273)=318K
V1/ T1 = V2 / T2
693/318 = V2/148
693×148 = 318 × V2
V2=102564/318
= 322.5mL
