Questions & Step-by-Step Solutions
What is the formula for calculating the number of moles?
Step 1: Identify the mass of the substance you have. This is usually measured in grams.
Step 2: Find the molar mass of the substance. This is the mass of one mole of that substance, usually found on the periodic table and measured in grams per mole (g/mol).
Step 3: Use the formula: Moles = Mass / Molar Mass.
Step 4: Plug in the values you have for mass and molar mass into the formula.
Step 5: Calculate the result to find the number of moles.
