To change from mass to moles, just follow these easy steps:
Identify the substance: Know what you are working with.
Find the molar mass: Look at the periodic table to see the weights of the atoms in the compound. Then, add them all together.
For example, for water (H₂O), the molar mass is about 18 g/mol.
Measure the mass: Weigh your sample using grams.
Use the formula: To convert mass to moles, use this formula:
Moles = Mass (g) / Molar Mass (g/mol)
Calculate: Just put your numbers into the formula!
It's really simple once you get the hang of it!
