Making the simplistic assumption that the dissolved NaCl(s) does not affect the volume of the solvent water, determine the constants m and b in the equation Molarity = m(density + b that relates the NaCl molarity to the NaCl(aq) density. Take the density of water to be 1.00 g/mL and the molar mass of NaCl to be 58.5 g/mol.

Properties of Water Station Lab Station 5. Density. Water is one of the few substances that are less dense as a solid than as a liquid. While most substances contract when they solidify, water expands. This property is due to the hydrogen bonding between water molecules. Part 1. Place the ice cube in the water. Describe what happened below.

Inside the bottle are two different liquids and two different plastics. These liquids and plastics all have different densities and as a result layer according to density (Figure 1). The two liquids in the bottle are isopropyl alcohol (D = 0.79 g mL-1) and salt water (17% NaCl by weight, D = 1.12 g mL-1).
