Write what you do in the lab step by step: Choose two pieces of glassware which will be a 50 mL beaker and a 10 mL graduated cylinder to find the density of DI water. We did three trails for the 50 mL- 1) an empty beaker weighs 29.871 g; with 20 mL of H2O weighing 46.973, 2) an empty beaker is 29.949 g; with 20 mL weighing 43.836, and 3) an empty beaker weighs 38.112 g; with H2O of 20 mL weighs 43.822g. For a 10 graduated cylinder we also did three trials- 1) with an empty beaker is 37.995l g with H2O of 6 mL weighs 43.836 g, 2) an empty beaker weighs 38.016 g; with 6 mL of H2O weighing 43.829 g, and 3) an empty beaker weighs g; with H2O it weighs 49.086 g.  You will need to calculate the density. Remember that density requires both the mass and volume of the substance you are measuring. The recorded temperature of the water is 21.7 C Include glassware used, chemicals used, amounts of chemicals used, concentrations ofchemicals, etc.

1. Imagine that have a cube of iron metal that you know has a mass of exactly 1.0000 grams because the cube was calibrated before you purchased it. You carefully measure the mass of this cube several times using the balance in your lab, but every time the balance indicates that the cube has a mass of 1.0900 grams. (1) State whether this balance be considered to be accurate, precise, both, or neither  (2) explain how you made your choice.

Part 1. Answer the following questions on the calculated density of water.a. How much did the density of water differ for each piece of glassware?b. Does your calculated density match better with the room temperature densityvalue provided?Part 2. How could reading the volume incorrectly affect your calculated density?

Gold can be hammered into extremely thin sheets called gold leaf. A 200-mg piece of gold (density = 19.32 g/cm3) is hammered into a sheet measuring 2.4 ft x 1.0 ft. %3D What is the average thickness of the sheet in meters? Hints: Calculate the volume of the sheet from its density and mass, and then use the volume relationship for a rectangular solid, V = length x width x thickness.
