Count is a numerical value, which express the coarseness or fineness diameter of the yarn and also indicate the relationship between length and weight the mass per unit length or the length per unit mass of that yarn.
February 15, Section: Determine the density of water. Obtain the vial of water from the lab. Record the known mass in grams and volume in mL of the cylinder. Weigh the cylinder to determine the mass of the vial plus the water, subtract the difference to determine the mass and record.
Determine the density of six unknown liquids. Obtain the six unknown samples from the lab. Record the known mass in grams and volume in mL of the cylinders. Weigh each cylinder to determine the mass of the vial plus the unknown, subtract the difference to determine the mass and record.
Obtain the mixture solution samples from the lab. Weigh each cylinder to determine the mass of the vial plus the solution, subtract the difference to determine the mass and record.
Complete a graph of your data.
The data should cover the entire graph i. Draw a line trend to average data points. Calculate slope of graph show all work on graph. Calculate the y intercept of graph show all work on graph.
Determine the composition of the unknown samples. Using the graph you made, find your unknown sample densities on the line trend and determine percentages of the solution.
Determine the densities of four solids aluminum, zinc, copper, and lead. Determine the mass of the solid by weighing it.
Record weight in in grams. Obtain a mL graduated cylinder and fill it with Read your value and record in mL. Subtract the above two values to determine volume and record in mL.
Repeat these procedures three times each for each solid. Using the data you recorded, determine the accuracy and precision and record. The measurements for copper were the most accurate, followed by aluminum and lead. With the measurements for zinc being the most accurate.Explain that in the lab rotation for today, students are going to investigate how adding and removing heat energy can affect the arrangement and motion of the particles in a substance including the state of mater, mass, volume, and density.
Measurement and Density.
are the basic units used for length, mass, and time. The unit for volume is derived. We will use a milliliter, which is equivalent to cm3, as our basic volume unit. Report the volume in the correct significant figures and include units.
Experiment 2 – Density Name _____ Lab Section _____ Experiment 2 – Density Introduction For this lab, the volume equals length times width times height will work for calculating the volume . Note: The volume of the object can be found by dividing the mass by the density, or multiplying the.
This lab will focus on quantitative observations, more specifically, measurements. the volume of a rectangle is defined by multiplying its length, width, and height.

• Density is defined by the ratio of the mass of a substance to its volume. • For an object to float, relative to its surroundings, it must be less dense than its surroundings.
