Answer : The number of moles of gas forced into a 3.5 L ball must be 2.28 moles.
Explanation :
Using ideal gas equation:
where,
P = pressure of gas = 23.3 psi = 1.58 atm
conversion used : (1 atm = 14.7 psi)
V = volume of gas = 3.5 L
T = temperature of gas =
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mole.K
Now put all the given values in the ideal gas equation, we get:
Therefore, the number of moles of gas forced into a 3.5 L ball must be 2.28 moles.
