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

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²
