Why is it important for us to leave the water for 5 minutes and determine the water's temperature? The density of water will vary with temperature. You want the water to equilibrate to room temperature in order to maintain consistent results. You want to wait so that the dissolved solids in the water settle to the bottom of the flask. It is impossible to determine the density of water below 20 °C with plastic beakers and cylinders so you need to wait for the water to warm up. It's not that important, we just want to stretch out the time of the experiment.
