Document Summary
No labs from september 4th to september 14th: No labs the week of the 4th, and the rst lab on the 11th was the safety quiz! In this rst experiment, we calculate the density of water experimentally, using a beaker, buret, and an analytical balance. Density density is recorded as mass volume . While using the analytical balance, measurements of mass should be recorded to the highest precision available. In this laboratory, record the measurement of mass to the nearest milligram: record the mass of an empty 50 ml beaker. The mass of the empty beaker will be the same for all trials: record the initial burette reading in the table, add between 1. 0 ml to 1. 5 ml of water to the beaker. Weigh the beaker and record the mass as beaker. Record this value in the table: from the mass of the beaker + water, subtract the weight of just the beaker.
