HELP ASAP PLEASE! THIS IS FOR STUDY ISLAND Metal Density (g/cm3) aluminum 2.70 zinc 7.14 iron 7.87 copper 8.96 silver 10.49 lead 11.34 mercury 13.55 gold 19.32 6 What is the identity of a sample that has a mass of 25.0 g and a volume of 2.38 cm3? A. aluminum B. iron C. silver D. lead

Copper

Explanation:

Given parameters:

Mass of metal = 25g

Volume of metal = 2.83cm³

Unknown:

Density of the metal  = ?

Solution:

Density is the mass unit volume of a substance. To solve this problem, use the mathematical expression below;

   Density  =

mass is the amount of substance in the metal

volume is the space occupied by the metal

 Now solve;

    Density  =   = 8.83g/cm³

The metal is Copper

it means there are 3 atoms of oxygen
