Water is a Polar Covalent Molecule
It consists of 2 Hydrogen molecules bonded to one Oxygen molecule and the two hydrogen atoms are not evenly distributed around the oxygen atom.
Answer:
m = 57.581 g
Explanation:
The actual yield or experimental yield of a reaction is always calculated using the theorical yield and the experimental, using the following expression:
%yield = Exp yield/theo yield * 100 (1)
If we know the theorical yield and the percent of yield, we can calculate the experimental or actual yield by solving the expression above:
Exp yield = %yield * theo yield/100
Replacing the values we have:
Exp yield = 81.1 * 71 / 100
Exp yield = 57.581 g
And this would be the actual yield of the reaction
