a hot air balloon hovers in space at an altitude of 400m. the air pressure is 0.95atm and the envelope holds 2,000,000L of air. How many moles of gas does it hold at 18 degrees celsius?

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
