The temperature of a 500.mL sample of gas increases from 150.K to 350.K.What is the final volume of the sample of gas,if the pressure and amount of gas in the container is kept constant?
A)210 mL
B)1170 mL
C)0.00950 mL
D)0.00474 mL
E)110 mL

Using Charles's law, we know that the volume of a gas is directly proportional to its temperature at constant pressure, so we can set up the following proportion:

Initial volume/Initial temperature = Final volume/Final temperature

V/150 = V₂/350

V₂ = (350/150) x V

V₂ = 2.33V

Final volume = 2.33 x 500 mL = 1,165 mL ≈ 1170 mL

Therefore, the correct answer is B.
