Use the atomic mass to calculate 72.5 g of neon to mole

Number of moles = 3.6 mol

Explanation:

Given data:

Mass of neon = 72.5 g

Moles of neon = ?

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of neon = 20.2 g/mol

Now we will put the values in formula:

Number of moles =  72.5 g/ 20.2 g/mol

Number of moles = 3.6 mol

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
