Using the ideal gas law, PV = nRT, we can calculate the number of moles of gas added to the balloon.Initial conditions:n1 = 2.3 molesV1 = 1.4 LFinal conditions:V2 = 7.2 LAssuming the temperature and pressure remain constant, we can write:n1/V1 = n2/V2Solving for n2, we get:n2 = n1 * V2/V1n2 = 2.3 moles * 7.2 L / 1.4 Ln2 = 11.8 molesTherefore, the number of moles of gas added to the balloon is:n2 - n1 = 11.8 moles - 2.3 moles= 9.5 moles
