ANSWER : 643.1 mL
STEPS:
V1/T1 = V2/T2
Volume of oxygen gas.
A sample of oxygen gas was initially at a temperature of 323 K.
The sample was heated to a new temperature of 377 K.
The volume of the sample at the new temperature of 377 K is 753.8 mL.
We want to find the volume of the sample at the initial temperature of 323 K.
To solve for the initial volume, we can use the combined gas law:
(V1/T1) = (V2/T2), where:
V1 is the initial volume of the gas
T1 is the initial temperature of the gas
V2 is the final volume of the gas
T2 is the final temperature of the gas
Rearranging the equation to solve for V1, we get: V1 = (V2/T2) x T1
Plugging in the values we know, we get:
V1 = (753.8 mL / 377 K) x 323 K
Solving for V1, we get:
V1 = 643.1 mL
Therefore, the volume of the oxygen gas sample at 323 K is approximately 643.1 mL.
