CHEM 101L eriment 1 Weighing Measurements Mass of known metal strip 56 Mass of unknown metal strip Lagtog Unknown 42 Volume Measurements Temperature of water 25 c Density of water G qazaY7glm Trial 1: Mass of water Calculated volume of water b49 2ml Trial 2: Mass of water Calculated volume of water Average volume tt Percent error 7.1926 mL Density of Solid Top loading balance/graduated cylinder Mass of cylindrical sample 13e 202 e Density 2.7 glunt Volume of cylindrical sample S ml Color/material AL (eilwer) Analytical balance/buret Mass of cylindrical sample 13 ase2g Density 2.3 volume of cylindrical sample: mL Page 1 of Experiment a 1 Report

Explanation / Answer

Ans 1.

Density is given as,

Density = mass / volume

So when the pipette is not correctly calibrated, and the volume dispensed is less than it should be , the density of the liquid calculated will be larger than the correct value, as volume is inversely related to the density.
