Answer:
6 moles of CuCl₂ will produced 4 moles of AlCl₃ .
Explanation:
Given data:
Moles of CuCl₂ = 6 mole
Moles of AlCl₃ produced = ?
Solution:
3CuCl₂ + 2Al → 2AlCl₃ + 3Cu
Now we will compare the moles of CuCl₂ with AlCl₃ .
CuCl₂ : AlCl₃
3 : 2
6 : 2/3 ×6 = 4 mol
So, 6 moles of CuCl₂ will produced 4 moles of AlCl₃ .
I'll be using dimensional analysis to help out.
2.5mol Na2O * ( X gNa2O / 1 molNa2O) = ? gNa2O
X gNa2O is the molar mass of the molecule. To find that we must add up the molar masses of all of the elements in the molecule.
There are 2 Na (Sodium).
And 1 O (Oxygen).
The Molar Mass of Na = 2 * 22.99 g/mol (It's multiplied by 2 because there are 2 of them in the molecule)
The Molar mass of O = 16.00 g/mol
If you are confused on where I found them. Let me enlighten you! I found them from a periodic table of elements.
Add those two values together to get a total molecular molar mass of:
38.99g/mol
2.5mol Na2O * ( 38.99 gNa2O / 1 molNa2O) = 97 gNa2O
