It stays roughly the same size. Electrons have a barely imperceptible mass so the overall mass of the atom is changed very little.
I will say it will be B. the maximum energy required to remove one electron from an atom... hope that help
Metabolism is when you don’t gain weight after eating a lot.
Avogadro Number of molecules is contained in 1 mole of water
6.02 * 10²³ molecules are contained in 1 mole of water.
2 * 10²² molecules will contain: (1* 2 * 10²²) / (<span>6.02 * 10²³)

≈ 0.0332 mole of Water.
Answer:
The molar mass of dry air = 28.94
Density = 1.29
Explanation:
Mm of N2= 28, Mm of O2= 32, Mm Ar= 39.9
78% of N2 by mole give = 0.78×28= 21.84
21% of O2 by mole give = 0.21× 32= 6.72
1% of At by mole give = 0.01× 39= 0.39
Hence overall molecular weight of air = 21.84+6.72+0.39= 28.94
Density = m/ v,
1- mole of air occupy 22.4dm^3 volume
Density= 28.94/22.4= 1.29
