Write the following measured quantities as you would record them using the correct number of significant figures based on the device used to make the measurements. a. Exactly 6 mL of water measured with a graduated cylinder that has a smallest scale marking of 0.1 mL b. A temperature that appears to be exactly 37 degrees using a thermometer with a smallest scale marking of 1 ° C c. A time of exactly nine seconds measured with a stopwatch that has smallest scale marking of 0.1 second d. Fifteen and one-half degrees measured with a protractor that has 1- degree scale markings

Mercury is a silver-coloured liquid. One quart of mercury weighs 28.4 pounds (lb).
What is the density of mercury in grams per millilitre? (1 L = 1.06 qt; 1 kg = 2.2 lb
In the lab a student measured the density of an Aluminum cylinder to be 2.89 g/cm3. The handbook value for the density of Aluminum at this temperature is 2.701 g/cm3. What is the percent error in the measurement? Report your answer using correct number of significant figures and units.
1. Write the following measured quantities as you would record them, using the correct number of significant figures based on the device used to make the measurement.
