Answer:

39.446L

Explanation:

since helium is ideal gas, we can use PV = nRT

P = pressure

V = volume

n = moles

R = gas constant

T = temperature in Kelvin

we are solving for V

V = [tex]\frac{nRT}{P}[/tex]

C to K temp transfer: K = C + 273, so K = 290 since C = 17

our gas constant is 0.08206 atm L/mol K, this gas constant r will change depending on what unit of pressure you are using (mmHg, atm, etc).

plug and chug

V = [tex]\frac{(2.3mol)(290K)(\frac{0.08206 atmL}{molK}) }{1 atm}[/tex]

canceling out units

V = [tex]\frac{2.3 * 209 * 0.08206L}{1}[/tex] = 39.446
