0.326 moles of gas
Explanation:
Knowing the volume of a gas at standard temperature and pressure (STP) we may calculate the number of moles of the gas using the following formula:
number of moles = volume / 22.4 (L /mole)
number of moles of gas = 7.3 (L) / 22.4 (L /mole)
number of moles of gas = 0.326 moles

It's how many are in the element's outer layer. The layers go: 2, 8, then 8.
Ex-6 electrons. 1 layer is 2, the next layer has 4 left. If that layer holds 8, you can do 8-4 and it has 4 valence electrons.
Ex-10 electrons. 1 layer is 2, the next layer has 0 left. It has 8 valence electrons because the outermost layer is full with 8.
ex-11 electrons. 1 layer is 2, the next layer is full as well. 2+8=10; it has 1 left. So that element has only one valence electron.
For Scientist Joseph Louis Gay-Lussac's law, temperature is measured on an absolute scale, specifically Kelvins or k. The formula may be expressed in P/T=k (P over T equals k). The answer to this question is 'kelvins'. I hope this helps.
