How many moles are there in 3.01x10^24 atoms of argon?

Explanation:

To convert from mole to atoms, we must use Avogadro's Number: 6.022*10²³. This number tells us the particles (atoms, ions, molecules, etc.) in 1 mole of a substance. In this case, the particles are atoms of argon.

Let's create a ratio.

Multiply by the given number of atoms.

Flip the fraction so the atoms of argon will cancel.

The original measurement of atoms has 3 significant figures, so our answer must have the same. For the number we calculated, that is the hundredth place. The 8 in the thousandth place tells us to round the 9 to a 0, which also rounds the 9 in the tenths place to a 0, then the 4 to a 5.

There are 5.00 moles of argon.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
