Density Hw Help Please?

By AntiVirus Posted in: RISING

When a piece of metal weighing 187.6 g is placed in a graduated cylinder containing 25.2 mL of water, the water rises to 33.8mL. What is the density of the metal?
Would you divide 187.6 by 33.8? Thanks.

    density is given as mass/volume
    so when metal is dipped in water it rises the water equal to its volume so its volume is (33.8-25.2=8.6ml)
    so we divide 187.6 g by 8.6 ml which give the density of metal
    so density of metal is 21.81 g/ml

    The volume of the metal is equal to the difference of the two volumes in the graduated cylinder = 33.8 – 25.2 = 8.6mL = 8.6cm3
    Now take 187.6g/8.6cm3

    Density = g/mL
    Subtract 33.8 from 25.2 to get correct mL then divide 187.6 by 33.8.
    33.8mL-25.2mL=8.6mL
    187.6g/8.6mL=21.81395349 ~ 22g/mL
