Molar mass is the mass of each element multiplied by subscript, then added together.

So, we’ll do

C = 12g x 12 = 144 g
H = 1g x 22 = 22 g
O = 16g x 11 = 176 g

The total of all of these is the molar mass: 342 g in a mol

The amount of mols of each element in each compound is likely equal to its subscripts.

C = 12 mols
H = 22 mols
O = 11 mols

For the atoms, you’ll multiply each one of the above by Avogadro’s number

Avogadro’s Number: 6.02 x 10^23 atoms/mol

Describe the ways in which ionic compound nomenclature differs from covalent compound nomenclature
Igoryamba

Answer:

Ionic compound are when electrons are given to another element, making one atom positive and the other negative, so they attract. Covalent compound is when both atoms share electrons with each other.
