Answer:
58.61mL
Step-by-step explanation:
V1 (initial volume) =?
T1 (initial temperature) = 320 K
V2 (final volume) = 50mL
T2 (final temperature) = 273 K
Using the Charles' law equation V1/T1 = V2/T2
The initial volume of the gas can obtained as follow:
V1/320 = 50/273
Cross multiply to express in linear form
V1 x 273 = 320 x 50
Divide both side by 273
V1 = (320 x 50)/273
V1 = 58.61mL
Therefore, the initial volume of the gas is 58.61mL
