We can use the ideal gas law: PV = nRT, where P is the pressure in atm, V is the volume in L, n is the number of moles, R is the gas constant (0.0821 L•atm/mol•K), and T is the temperature in K.

First, we need to convert the temperature to K:

97 °C + 273.15 = 370.15 K

Next, we need to convert the pressure to atm:

365 torr ÷ 760 torr/atm = 0.480 atm

Now we can plug in the values:

(0.480 atm) V = (0.15 mol)(0.0821 L•atm/mol•K)(370.15 K)

V = (0.15 mol)(0.0821 L•atm/mol•K)(370.15 K) / (0.480 atm)

V ≈ 9.5 L

Therefore, the answer is D) 9.5.

The Volume of 0
