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.

Explanation:
The substances that will conduct electricity is the NaCl solution. Sodium chloride in its solid form do not conduct electricity since the compound is stable and bonded well so there are no available charge carriers. However, when this salt is dissolved in water, it ionizes or dissociates into sodium ions and chloride ions. On the other hand, solid sugar and an aqueous solution of sugar do not conduct electricity since the bond involved in this compounds is covalent, no ionization would occur. When sugar is dissolved in water it stays as a molecule so there will be no available charge carriers to let electricity flow.
