You have a mixture that contains 0.380 moles of Ne(g), 0.250 moles of He(g), and 0.500 moles CH4(g) at 400 K and 7.25 atm. What

The atomic number corresponds to the number of protons

Protons are denoted as P and Electrons as E P = E

The atomic mass equals the sum of Neutrons and Protons

Atomic number = atomic mass = neutrons

P = E

Atomic mass - atomic number = Neutrons

Example:

Calcium consists of 20 Protons 20P = 20E

Atomic mass - atomic number = neutron count:)

Answer:

The categorization of strong, weak, and non-electrolytes is detailed below, based on the examples presented in the question.

Explanation:

A strong electrolyte fully dissociates or nearly so in an aqueous environment; typically, strong acids, bases, and salts fall under this category. Examples of strong electrolytes include:

• Hydrochloric acid, HCl
• Calcium hydroxide, Ca(OH)2
• Potassium chloride, KCl

A weak electrolytepartially ionizes in solution; weak acids and bases are primary instances. Examples consist of:

• Methylamine, CH3NH2
• Hydrofluoric acid, HF

A non-electrolytedoes not dissociate in an aqueous medium. Examples of non-electrolytes are:

• Sucrose, C12H22O11
• Methanol, CH3OH
