Are electrons located at the outermost shell of an atom
Answer:
m = 31.284 grams
Explanation:
Given that,
The dimension of a magnesium block is 2.00 cm x 3.00 cm x 3.00 cm.
The density of magnesium is, d = 1.738 g/cm³
We need to find the mass of the magnesium block. We know that the density of an object is given by its mass per unit its volume. So,

So, the mass of the block is 31.284 grams.
HCl(aq) + KOH(s) --> KCl(aq) + H2O(l)
Because subatomic particles ARE what make up atoms.
