Density measures how tightly packed particles are.
If particles are tightly packed together, they will be more dense.

Answer:
857.2947
Explanation:
You start with what you’re given 82g of H20 and multiply by 1 mole and the actual grams of h20 which is 18.0 then you do the mole. 1 mol of O2 and 2 mol of H2O times 6.02 x 10^23
Most elements tend to have the same number of electrons and protons. This gives the element a neutral charge, aka no charge at all.
Here is an example:- Flourine
7 electrons and 7 protons
