Moles (solid) = | mass (g)/ RAM |
Mass= | moles x RAM |
What is the definition of Avogadro's Constant? | The number of atoms per mole of the Carbon-12 isotope. |
Moles (gas) = | volume / molar gas volume |
When using decimeters, you need to divide by... | 1000 |
When using centimeters, you need to multiply... | 1000 |
