Answer:</h3>
5.89%
<h3>
Explanation:</h3>
We are given;
- Mass of the solute, LiOH as 40.1 g
- Mass of the solvent, H₂O as 681 g
We are required to calculate the mass percent composition of solution;
- But; How do we calculate the mass percent composition of a solution?
- We use the formula;
- Mass composition of a solution = (Mass of solute/mass of solution) 100%
Mass Percent = (40.1 g/681 g)× 100%
= 5.888 %
= 5.89%
Therefore, the mass percent composition of the solution is 5.89%
The answer would be A be cause it is the most reasonable answer
MgCl2 because it is the only option in which a metal appears with a nonmetal. In this case, the metal transfers electrons to the nonmental because the metal has a lower ionization energy.
