Problem: An experiment was performed in which an empty 100-mL graduated cylinder was weighed. It was weighed once againafter 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 sand–methanol 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 gMass of cylinder plus dry sand              37.3488 gMass of empty cylinder                         22.8317 gVolume of dry sand                               10.0 mLVolume of sand plus methanol             17.6 mLVolume of methanol                              10.00 mL

Problem Details

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 sand–methanol 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
