Question

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

Answer 1

Number of moles = 3.6 mol

Step-by-step 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
