No. A voltage reading is a result of a difference in cell potential of the cells. Even if you added the volume, it would still not affect because what matters is the concentration of the ions which give the potential gradient. All you did was add the quantity in terms of volume but the substance in it is still the same.
Answer:
100 g of water has the highest number of moles
Explanation:
Recall that the number of moles is obtained as given mass/formula weight
For HCl;
number of moles = 100g/36.5g/mol = 2.7 moles
For H2O;
number of moles = 100g/18g/mol = 5.5 moles
For MgCO3
number of moles = 100g/84.3 g/mol = 1.2 moles
For AlCl3
number of moles = 100g/133.3g/mol = 0.75 moles
For NaCl
number of moles = 100g/58.4 g/mol = 1.7 moles
The reason why it is not considered this is because the material was made in a lab, not through nature, which is what is required to be considered as a true mineral.
