Answer:
Because the same amount of sugar is still there. The solid sugar crystals break apart in water as the sugar dissolves, but the individual sugar particles or molecules are still present and do not change as a result of dissolving in the water. The combined mass of the sugar and water shouldn't change.
Answer:
Percent error = - 8.1 %
Explanation:
Given data:
Actual mass = 27.20 g
Theoretical mass = 25.01 g
Percent error = ?
Solution:
Formula:
Percent error = theoretical value- actual value/ actual value × 100
Now we will put the values in formula.
Percent error = 25.01 - 27.2 / 27.2 × 100
Percent error = -2.19 / 27.2 × 100
Percent error = -0.081 × 100
Percent error = - 8.1 %

M = mols of solute / L of solution
Convert .50 g Na to mols Na by dividing by 22.99 and then dividing that by 1.5, which gives you a 0.014 M solution.
