How do you calculate the moles of an element in a compound?

Once you've found the molecular weight, you know the weight of one mole of a compound. To find the number of moles in a sample, simply weigh it and divide the weight by the molecular weight. The quotient is equal to the number of moles.

How do you find moles from grams?

You have three steps to convert mole values to grams.

  1. Calculate how many moles are mentioned in the question.
  2. Find the molar mass of the substance.
  3. Multiply both the values.
