Answer:

Explanation:
To convert from moles to particles, we must Avogadro's Number.

This number tells us the number of particles (atoms, ions, molecules, etc.) in 1 mole of a substance. In this case, it is the particles of calcium in 1 mole of calcium.

We can use Avogadro's Number as a ratio or fraction.

Multiply this by the given number of particles (3.57*10³²).

Flip the fraction so the particles of calcium will cancel out.




There are <u>592,826,303.6 moles</u> of calcium in 3.57*10³² particles of calcium.

The person who knows how to play the piano has more authority to teach the piano than a dance teacher.
