Two descriptions for a sub-atomic particle are listed below: description 1: non-charged particle description 2: located inside the nucleus of an atom which sub-atomic particle or particles fit these descriptions? electrons only neutrons only electrons and protons protons and neutrons

Description 1: non-charged particle: Neutrons only

Description 2: Located inside the nucleus of an atom: Protons and neutrons

Explanation:

The subatomic particles of an atom are smaller than the atom, and the main are:

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
