Hello there! :)

[tex]\huge\boxed{\text{11.315 mol}}[/tex]

We can use dimensional analysis to convert from grams to moles. Use the atomic weight of argon to determine the amount of g/mol.

[tex]452g * \frac{1 mol}{39.948g} = \frac{452}{39.948}mol = 11.315mol[/tex]

Therefore, there are approximately 11.315 moles in 452 grams of argon.

The number of moles that are contained in the given mass of argon is equal to 11.32 moles.

Given the following data:

Mass of argon = 452 grams.

Scientific data:

Molar mass of argon = 39.948 g/mol.

How to calculate the moles of a compound?

In this exercise, you're required to determine the number of moles of argon that are contained in the given sample.

Mathematically, the number of moles contained in a given mass of chemical compound is calculated by this formula:

[tex]Number \;of \;moles = \frac{mass}{molar\;mass}[/tex]

Substituting the given parameters into the formula, we have;

Number of moles = 452/39.948

Number of moles = 11.32 moles.
