Grams and Values

• Identify the grams of eliminate (compound) given.

• Record the values involved in the calculation.

Calculation of Compound's Mass

• If the gram of magnesium is given, document this as a part of the calculation.

• If both magnesium and oxygen grams are provided, sum these to find the total mass of the compound.

Percent to Find Parts

• If a percent is provided, and the whole is known, use this to find the specific part by plugging in the values.

Empirical Formula Steps

• Write down the empirical formula process on your pen sheet.

• The following steps will guide the calculation:

  • Step 1: Calculate and write the molecular formula weight.

  • Step 2: Determine if the formula weight is a whole number.

  • Step 3: If not a whole number, determine the multiplier needed to convert it into one (usually by finding the closest whole number).

  • For example, multiply everything by 2 if required.

Additional Notes

• Ensure each part of the calculation is done uniformly across the formula. What you do to one part must be done to all components of the empirical or molecular formula.
