Question

the following measurements were made to determine the density of a material whose value was, according to the handbook of chemistry and physics, 1.15 g/ml.

trial 1	0.95 g/ml
trial 2	1.16 g/ml
trial 3	1.26 g/ml

what kind of accuracy does this display?

• high
• low

Explanation:

Accuracy refers to how close measured values are to the true value (1.15 g/mL here). Trial 1 (0.95) is far from 1.15, Trial 2 (1.16) is close, but Trial 3 (1.26) is also off. Since not all trials are close to the true value, and one is significantly different, the overall accuracy is low.

Answer:

Low
