Your teacher has just asked you to measure out 2.25 moles of Sodium Bicarbonate. Sodium Bicarbonate has a Molecular Formula of NaHCO3. Using a Periodic Table, calculate the molecular mass of Sodium Bicarbonate to 2 decimal places. Then calculate the amount that will need to be measured out, in grams, to get your 2.25 moles for your teacher. You get curious as you are weighing out the 2.25 moles and wonder how many molecules are there in your 2.25 moles of Sodium Bicarbonate sample. What is the molecular Mass of Sodium Bicarbonate?
