(choose chapter or problem)

An experiment was performed in which an empty 100-mL graduated cylinder was weighed. It was weighed once again after it had been filled to the 10.0-mL mark with dry sand. A 10-mL pipet was used to transfer 10.00 mL of methanol to the cylinder. The sandmethanol mixture was stirred until bubbles no longer emerged from the mixture and the sand looked uniformly wet. The cylinder was then weighed again. Use the data obtained from this experiment (and displayed at the end of this problem) to find the density of the dry sand, the density of methanol, and the density of sand particles. Does the bubbling that occurs when the methanol is added to the dry sand indicate that the sand and methanol are reacting?Mass of cylinder plus wet sand 45.2613 g Mass of cylinder plus dry sand 37.3488 g Mass of empty cylinder 22.8317 g Volume of dry sand 10.0 mL Volume of sand plus methanol 17.6 mL Volume of methanol 10.00 mL
