Exhibit 1-1 Consider the following figure that is a blow-up view of a region of a 50 mL burette to answer the following question(s). The density of ethanol was measured in two steps. The first step involved measuring its volume using a burette. The mass of this volume was then measured.
-Refer to Exhibit 1-1. Look carefully at the figure above of the burette. Read the burette at the bottom of the meniscus as accurately as possible to the proper number of significant digits. What volume should be recorded for the volume delivered from this burette assuming the liquid level started at the top as zero milliliters?

The correct reading is at the bottom of the meniscus. The meniscus appears to be just slightly above the 35.8 mL mark, making 35.75 mL the most accurate reading given the options. Burettes are typically read to two decimal places, with the last digit estimated.
