Please help!!!! I will give brainliest if correct!!!
Identifying a substance based on density lab:

Metal Density (g/mL)
Cu 8.92
Al 2.702
Pb 11.3437
Zn 7.14
Fe 8.39
Sn 7.28

You are given a metal block with a mass of 62.44g and a mass of 7cm3. What is the identity of your block? How did you know?

    Answer:

    The density ρ of metal block is 8.92g/cm³

    So from the given density table this corresponds to copper which has density of 8.92(g/mL)

    Explanation:

    Oh yeah, I got the correct unit update,

    Now this problem bothers on the density of substances

    We know that the density of a substance is expressed as

    Density ρ= mass/ volume

    Given data

    Mass of metal block m= 62.44g

    Volume of metal block v= 7 cm³

    Hence we can find the density of the metal block by plugging in our data into the expression for density

    ρ of metal block = 62.44/7

    ρ of metal block = 8.92g/cm³

    The block is a copper block
