When the sugar cubes are <span>placed in water, then, the mixture will be affected by stirring the water.
By stirring the water, the sugar cubes dissolve in water. The molecules of sugar cubes interact with water molecules in the jar. But when more sugar is added to the water, there comes a saturation point when no more sugar will be dissolved and it will settle down. Then, by raising the temperature the settled sugar will be dissolved too.</span>
The molarity of a solution that has 0.05 moles of HCL are added to 2 L of H2O is 0.025M.
<h3>How to calculate
molarity?</h3>
The molarity of a solution can be calculated using the following formula:
M = n/V
Where;
- M = molarity
- n = number of moles
- V = volume
M = 0.05/2
Molarity = 0.025M
Therefore, the molarity of a solution that has 0.05 moles of HCL are added to 2 L of H2O is 0.025M.

I think the answer is chemical energy
Explanation:
Answer:
4.8 %
Explanation:
We are asked the concentration in % by mass, given the molarity of the solution and its density.
0.8 molar solution means that we have 0.80 moles of acetic acid in 1 liter of solution. If we convert the moles of acetic acid to grams, and the 1 liter solution to grams, since we are given the density of solution, we will have the values necessary to calculate the % by mass:
MW acetic acid = 60.0 g/mol
mass acetic acid (the solute) = 0.80 mol x 60 g / mol = 48.00 g
mass of solution = 1000 cm³ x 1.010 g/ cm³ (1l= 1000 cm³)
= 1010 g
% (by mass) = 48.00 g/ 1010 g x 100 = 4.8 %
A period is horizontal; the elements gain 1 proton for each space moving left to right.
A group is vertical; the elements in each group have the same number of electrons in the valence shell(outer orbital).
