How to Calculate Molar Mass Practice Problems

  • Опубликовано: 16 апр 2014
  • We will learn how to calculate the molar mass of a compound by using its chemical formula. Molar mass is a quantity that is very similar to molecular mass, molecular weight, formula mass, and formula weight. In order to calculate molar mass, we look at the formula to determine how many atoms of each type are in it, and then look at the periodic table to determine the atomic mass of each of the atoms. We will look at compounds containing polyatomic ions, and also hydrate compounds.

    I love you, I love you and I love you!!!!!!!!!!!! I can't believe I was about to quit my chemistry class until I watched your explanations. You saved me from my frustration and from that man who calls himself a professor. My professor is horrible I never understand a single material he teaches in class. All of your videos have been saving my neck, day by day. AGAIN, I LOVE YOU! God keep blessing your intelligence and capacity to explain chemistry.

    24.31+32.07+64.00+14.14+112.00= 246.52...Or is there something I did wrong?
