One million argon atoms is how many mol of argon atoms? (2 significant figures)

One million argon atoms is equivalent to 1.7 × 10⁻¹⁸ moles of argon atoms.

To convert one million (10⁶) argon atoms to moles of argon atoms, we will use Avogadro's number: there are 6.02 × 10²³ argon atoms in 1 mole of argon atoms.

1.66 * 10^-18 mol of Argon

Explanation:

Avogadro says 1 mol of anything has 6.022* 10^23 atoms/particles. Thus using this principle, 1 million argon atoms will have

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire
