A gas sample has a temperature of 20. ∘C with an unknown volume. The same gas has a volume of 449 mL when the temperature is 89 ∘C, with no change in the pressure and amount of gas. Part A What was the initial volume, in milliliters, of the gas? Express your answer using three significant figures.
Initial Final
T1 = 20+273 = 293K T2 = 89+273 = 362K
V1 = V2 = 449ml
V1/T1 = V2/T2
V1 = V2T1/T2
= 449*293/362
= 363ml
The initial volume = 363ml >>>>answer
