Answer:
1.73 Molar
Explanation:
The formula is Molarity=moles of solute/liters of solution, which can be written in whatever way you prefer, and examples include: M=N/V or M=mol/L.
M=N/V
M=
Divide 5.63 by 3.25. When you calculate this, you get 1.73, therefore your answer is 1.73 molar.
The question is incomplete, here is the complete question:
The given chemical reaction is:
What is the theoretical yield of Calcium if we begin with 12.6 grams of Aluminium?
<u>Answer:</u> The theoretical yield of copper is 44.48 grams
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
Given mass of aluminium = 12.6 g
Molar mass of aluminium = 27 g/mol
Putting values in equation 1, we get:
The given chemical equation follows:
By Stoichiometry of the reaction:
2 moles of aluminium produces 3 moles of copper
So, 0.467 moles of aluminium will produce = of copper
Now, calculating the mass of copper from equation 1, we get:
Molar mass of copper = 63.5 g/mol
Moles of copper = 0.7005 moles
Putting values in equation 1, we get:
Hence, the theoretical yield of copper is 44.48 grams
