I Can you help me understand how I'm supposed
to find the predictions of the following solutions?
I know this is an Ionic compound and that
the more ions in a solution means it is able
to carry a charge, right?

The light are not matching up with the scale
So I'm confused about what I should be…
Label these peaks in H- NMR and C- NMR
Complete the following table. The only density needed is already given. Show your
calculations in a neat and easy-to-follow manner in the space below the table. All units
should be included and significant figures should be given close attention. Be sure to notice
that the amount of material should be in millimoles rather than moles, and the theoretical
mass of the product should in milligrams rather than grams.
