The answer is 39.948.

Also Know, what is the mass of one mole of argon? The molar mass of argon is equal to 39.948 grams-per-mole, or 39.948 g/mole.

Secondly, how many moles are in 22 grams of argon?

0.55 moles

How do I calculate moles?

Start with the number of grams of each element, given in the problem. Convert the mass of each element to moles using the molar mass from the periodic table. Divide each mole value by the smallest number of moles calculated. Round to the nearest whole number. This is the mole ratio of the elements and is.
