You are given a marble by your instructor and are asked to measure its density. Unfortunately, marbles roll when placed on a balance pan, so you decide to use a beaker to hold the marble while you measure its mass. An empty beaker has a mass of 31.86 g. You place the marble into the beaker and find a new mass of 42.96 g. You then drop the marble into a graduated cylinder that contains 26.7 mL water and record the new volume of water as 29.7 mL. What is the density of the marble

Ace Burke · Answer 1

mass of marble = 42.96 - 31.86

= 11.1 g

volume of marble = 29.7 - 26.7

= 3 mL

density = mass / volume

= 11.1 / 3 gm / ml

= 3.7 gm / ml
