Multistep Conversions!

Multistep conversions can be used to figure out the mass, moles, volume and even molecules and atoms in a certain chemical equation.

Mass to Volume:
Step 1: Convert mass to moles.
Step 2: Convert moles to volume.

Mass to Molecules:
Step 1: Convert mass to moles.
Step 2: Convert moles to molecules.

Mass to Atoms:
Step 1: Convert mass to moles.
Step 2: Convert moles to molecules.
Step 3: Convert molecules to atoms.

Volume to Mass:
Step 1: Convert volume to moles.
Step 2: Convert moles to mass.

Volume to Molecules:
Step 1: Convert volume to moles.
Step 2: Convert moles to molecules.

Volume to Atoms:
Step 1: Convert volume to moles.
Step 2: Convert moles to molecules.
Step 3: Convert molecules to atoms.

Examples:
1. 5.1g x 1mol/79.9g x (6.02x10^23)/1mol = 3.8 x 10^22
2. 3.62x10^24 x 1mol/(6.02x10^23) x 320g/1mol = 192g
3. 2.94x10^24 x 1mol/(6.02x10^23) x 142g/1mol = 693g
