Initial temperature =77 degree
Final temperature =77-20 =57 degree
We know by Charles law,
V1/T1=V2/T2
=>V1/77=900/57
=>V1=(900*77)/57
=1215.78
Hence, the initial volume of the gas is 1215.78 ml.
Final temperature =77-20 =57 degree

Answer:
Let V1 be the initial volume of the gas = x
T1 be the initial temperature of the gas in K =273+77
V2 be the final volume of the gas = 900ml
T2 be the final temperature of the gas in K = 273+(77-20) = 330K
By Charles Law. V1/T1 = V2/T2
Substituting the value: x/350 = 900/330
therefore, V1 = 350/330*900=954.54ml
