Answer:
Explanation:
The way to do this is through a mole to gram conversion using the molar mass of calcium hydroxide. The molar mass of calcium hydroxide can be found using your periodic table where you add the molar mass calcium + 2 times the molar mass of oxygen + 2 times the molar mass of hydrogen. When you do this you end up with a total molar mass of 74.093 g/mol.
Now we can do a conversion to find the amount of grams produced (mass) from 3.397 moles.
So lets start with our moles and put that in a fraction.
[tex]\frac{3.367mol(Ca(OH)_{2}) }{1}[/tex]
So to cancel out our moles we need moles on the bottom.
We can think of the molar mass as being written as:
[tex]\frac{74.093g}{mol}[/tex]
So in this case we just need to multiply directly because our moles will cancel
Now we will have:
[tex]\frac{3.367mol(Ca(OH)_{2} }{1} (\frac{74.093g}{mol})[/tex]
This leaves us with
3.367 x 74.093 = 249.47 grams of calcium hydroxide.
