Explanation:
The water solution of PbCl2 is poor. It also has 2 distinct dissolving properties. In cold water, this will not dissolve easily.It is water-insufficiently soluble. And that in cold water, it is indeed insoluble. That's why we know that all energy should be available for a solid to dissolve in the liquid to counteract that attractive force between the ions in the grid.
Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
<u>Explanation:</u>
The properties and behavior of many solutions depend not only on the nature of the solute and solvent but also on the concentration of the solute in the solution. Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution:

Therefore, Number of moles of solute in 16.55 mL of 0.1475 M M2Cr3O7 is 0.00244 moles.
