Question

How many moles are in 22 grams of argon

Answer 1

number of moles are the amount of substance of an element .
number of moles can be calculated as follows;
number of moles = mass present / molar mass of element
molar mass of Ar - 40 g/mol
number of moles of Ar = 22 g / 40 g/mol = 0.55 mol .
there are 0.55 mol of Ar

Answer 2

Step-by-step explanation:

It is known that number of moles equal mass divided by molar mass.

Mathematically, Number of moles =
`(mass given)/(molar mass)`

Since, it is given that mass is 22 grams and molar mass of argon is 40 g/mol.

Therefore, Number of moles =
`(mass given)/(molar mass)`

=
`(22 g)/(40 g/mol)`

= 0.55 mol

Thus, we can conclude that there are 0.55 moles in 22 grams of argon.
