The density of the unknown solid was 7 g/mL whereas the density of the unknown liquid was 0/mL, and the density of the unknown salt solution was 1 g/mL. In the first part of the experiment, the measurements were very accurate.
15 Οκτ 2022 · The volume of a liquid can be directly measured with specialized glassware, typically in units of milliliters (mL) or liters (L). In this lab, a beaker, two graduated cylinders and a burette will be used to measure liquid volumes, and their precision will be compared.
2 Μαρ 2022 · This is a collection of free volume conversion worksheets. It includes both metric and English units of volume. For example, units include cubic centimeters (cm 3), cubic meters (m 3), liters, milliliters, cubic feet (ft 3), quarts, and gallons.
report measurements accurately and precisely to convey information to others. In this lab you will to learn how to read scientific instruments and report the results with the correct number of significant figures. Measurements contain certain and uncertain digits.
Objectives. Recognize and utilize common glassware and equipment. Prepare solutions of different densities to identify unknowns. Learning Outcomes. Understand the nature of units of measurement and apply proper significant figure rules. Differentiate between accuracy and precision.
Length = cm 3. What is this length in millimeters? Length = mm 4. Divide the centimeter measurement obtained in #2 by five inches to obtain the cm to inch ratio. This will give you a conversion factor to convert centimeters to inches and vice-versa. Calculation: cm 5.00 in = Answer = cm in B Temperature
For conversions within the metric system, you must memorize the conversion (for example: 1000 mL = 1 L, or 1000 g = 1 kg should be memorized) Remember that metric conversions are exact ratios and thus will not limit your significant digits for the answer.
