Question

4.

	erlenmeyer flask	beaker
volume of water from glassware as measured in the graduated cylinder	______ml	______ml
error in volume the error is the difference between volume reported above and the expected volume	______ml	______ml
% error = \\(\frac{error\\ in\\ volume}{volume\\ measured\\ in\\ graduated\\ cylinder}\\) x 100	______%	______%

1. which piece of glassware will give you a more accurate measure of liquid: the graduated cylinder, the erlenmeyer flask, or the beaker? (5 pts.)

Explanation:

To determine which glassware is more accurate, we analyze the % error values. A lower % error indicates higher accuracy. From the table, the Erlenmeyer flask has a % error of ~3.1% and the beaker has 7.5%. Graduated cylinders are designed for precise volume measurement, with typical % error lower than flasks and beakers (which are for holding/mixing, not precise measurement). So the graduated cylinder is more accurate.

Answer:

The graduated cylinder will give a more accurate measure of liquid.
