The concentration of solutions is measured in a unit called moles (M). Now that you know this, use the picture to answer questions #1 - #5. The picture shows a red blood cell floating in a
solution in a beaker. The picture also shows the concentrations of salt inside the red blood cell
and the concentration salt in the beaker.

How do water’s relative densities as a solid and a liquid differ from that of most other substances? water’s solid and liquid forms have different densities, while most other substances have solid and liquid forms with similar densities. water’s solid and liquid forms have similar densities, while most other substances have solid and liquid forms with different densities. water’s liquid form is less dense than its solid form, while the opposite is true of most other substances. water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.
