Answer:
81 gm
Explanation:
The mass of 1 mole is 27 g
So, Mass of 3 moles of Aluminium would be 3 × 27 = 81 gm..Thus mass of 3 Moles of Aluminium is 81 gm.
The stars in the solar system are made of hydrogen and helium
[Ne]3s^23p^6 ( answer D) represent a sample of an octet. Octet is the tendency of an atom to have eight electrons in the valence shell. [Ne]3s^2 3p^6 is an octet since its valence electron that is3s^23p^6 has eight electrons.
