Answer:
156.7mL
Explanation:
First we need to find the number of mole of He. This can be achieved by doing the following:
Mass of He from the question = 30g
Molar Mass of He = 4g/mol
Number of mole = Mass /Molar Mass
Number of mole of He = 30/4
Number of mole of He = 7.5moles
Now, we can obtain the volume as follows:
P = 1.15 atm
T = 20°C = 20 + 273 = 293K
R = 0.082atm.L/Kmol
n = 7.5moles
V =?
Recall: PV = nRT
V = nRT/P
V = (7.5 x 0.082 x 293)/1.15
V = 156.7mL
Therefore, the volume that can be filled to that pressure is 156.7mL

No I don't think it works that way. What you could do is drink one energy drink, wait 5 hours and then drink another.
