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

Explanation:

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

Mathematically,  Number of moles = $\frac{mass given}{molar mass}$

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

Therefore,  Number of moles = $\frac{mass given}{molar mass}$

                                                 = $\frac{22 g}{40 g/mol}$

                                                 = 0.55 mol

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