## How many moles are in 5.0 grams CaO?

Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

## How do you find moles of CaO?

You need to determine the molar mass of CaO , which is the sum of the atomic weights of each element on the periodic table in grams/mole, or g/mol. Determine the number of moles by multiplying the given mass of CaO by the inverse of its molar mass.

## How many moles are 5 grams of calcium atomic mass of calcium 40u?

Grade 10. Molar mass of Calcium=40.078 g/mol. So numbers of moles =5.00/40.078=0.125 mol.

## How do you calculate CaO?

CAO Calculation: To determine if an operation is a CAO, take the total AEU’s per farm and divide by the acres suitable for the application of manure. Include all acreage (owned AND rented) that is suitable for the application of manure, and is under the management control of the operator.
