Sagot :
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
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
Explanation:
It is known that number of moles equal mass divided by molar mass.
Mathematically, Number of moles = [tex]\frac{mass given}{molar mass}[/tex]
Since, it is given that mass is 22 grams and molar mass of argon is 40 g/mol.
Therefore, Number of moles = [tex]\frac{mass given}{molar mass}[/tex]
= [tex]\frac{22 g}{40 g/mol}[/tex]
= 0.55 mol
Thus, we can conclude that there are 0.55 moles in 22 grams of argon.
