Question

A chemist has a block of copper metal (density is 8.96). They drop the metal into a graduated cylinder containing water, and find the volume change is 2.90 mL. What is the mass of the block , in grams?​

Answer 1

Answer:

26g

Explanation:

Given parameters:

Density  = 8.96g/cm³

Volume of metal = 2.9mL

    Since 1mL  = 1cm³;

          Volume  = 2.9cm³  

Unknown:

Mass of the blocks in grams  = ?

Solution:

Density is the mass  per unit volume of a substance;

   Mass  = density x volume  = 8.96 x 2.9  = 26g
