Question

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

    Answer:

    Explanation:

    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
