Safety concerns: 10. Wear closed toed shoes to prevent foot injuries. 11. Where goggles when working with the glass (beaker and graduated cylinder). 13. Do not be involved in horseplay because you might cause the graduated cylinder and beaker to break. 34. If you break the graduated cylinder or beaker never use just your hands use a brush and dustpan to clean up, throw away the glass as told by the teacher. Procedure: Part I: Rectangular Solid (Wooden Block) Mass: In order to find the mass of the rectangular solid utilize the balance.Document the mass by rounding to the closest 0.1 g in the data table underneath. Volume: Find out the length, width, and height of the rectangular solid by utilizing the metric ruler. Document these by rounding to the closest 0.01 cm. Utilize the formula for…show more content…
What pieces of laboratory equipment would you use to measure the properties needed to determine the density of a substance? The piece of laboratory equipment needed to find mass is a balance and for volume a graduated cylinder. 3. Using the properties stated in question 1, write the formula for density. D=m/v 4. What two sets of units can be used to describe density? Why are they interchangeable? The two sets of units used to describe density are grams (g) and milliliters (mL). They are interchangeable because 1g=1mL. 5. A solid block with a length of 6.0 cm, a width of 3.0 cm, and a height of 3.0 cm has a mass of 146 g. What is the block’s density? Show all work. V=lxwxh v=6.0cmx3.0cmx3.0cm= 54cm D=m/v d= 146g/54cm= 2.7g/cm3 6. To determine the density of an irregularly shaped object, a student immersed the object in 21.2 mL of water in a graduated cylinder causing the level of the water to rise to 27.8 mL. If the object has a mass of 22.4 grams, what is the density of the object? Show all work. 27.8mL- 21.2 mL=6.6 mL D=m\v d= 22.4grams/ 6.6 mL=
