What is Avogadro's Number

6.023×10^23

What does Avogadro's number represent

The number of units in one mole of a substance

What is a mole

6.023×10^23 units of a substance

An atom's AMU equal to its Atomic Weight.

True

A molecule's Molar Mass equal to the sum of its atoms' Molar Masses.

True

How many units of a substance are in 1 mole of it

Avogadro's number (6.023×10^23)

An atom's AMU is equal to its Molar Mass in grams.

True

How do you calculate the number of formula units in a sample

Divide the sample mass by the formula's molar mass and multiply it by Avogadro's Number.

How do you calculate what percent a number is of another number

Divide the part by the whole Carbon-12 weighs how many AMU
