B)1170 mL
C)0.00950 mL
D)0.00474 mL
E)110 mL

According to Charles's Law, at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin units. Thus, we can use the equation:

(V1/T1) = (V2/T2)

where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.

Plugging in the given values, we get:

(V1/150) = (V2/350)

To solve for V2, we can cross-multiply and simplify:

V2 = (V1)(350/150) = (500 mL)(2.333) = 1165 mL

Therefore, the final volume of the sample of gas is 1170 mL (closest to option B).
