| What exactly is a Mole? | -Simply a Number, a very large one: 6.022 x 10 to the power of 23
-Its: 602,200,000,000,000,000,000,000
-A mole is done by Avogadro's Constant |
| What is Avogadro's Constant say? | -When you get x number of Atoms or Molecules of any Element or Compound, then it will exactly weigh the Same Number of Grams as the Atomic Mas, or Relative Formula Mass |
| So what does 1 Mole of Atoms/ Molecules mean? | -Means the Mass in Grams will be the Relative Formula Mass [Compound] or Atomic Mass [Element] |
| So how many moles in 12g of Carbon? | -1
-This is because the Atomic Mass of Carbon is 12. |
| How many atoms are in 5 Moles of Oxygen Gas? [O2] | -1st Multiply Avogadro's Constant by the Number of Moles you need to fine
[6.022 x 10 to the power of 23 X 5= 3.011 x 10 to the power of 24]
-2nd: Multiply your answer by 2 In this Case, because there is 2 Atoms in a Molecule of Oxygen Gas
[3.011 x 10 to the power of 24 X 2 = 6.022 x 10 to the power of 24] |
| How can you find the Mass of an Atom in a Element [Using Moles]
Use an Example with finding an Atom of Iron | -Simply divide the Relative Atomic Mass, by Avogadro's Constant
-Mass of an Atom=Atomic Mass divided by Avogadro's Constant
-55.8 [Ar of Iron] divided by 6.022 x 10 to the power of 23 is equal to 9,27 x 10 to the power of -23g |
| What does the Formula of Number of Moles show? What is it? | -Shows how many Moles in a given Mass
-Number of Moles = Mass in Grams [Element or Compound]
