The metal was known to have a density of 5.78 g/mL. A graduated cylinder was filled with 22.3 mL of water and after the metal was added the volume was 24.7 mL. What is the mass of the metal?

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density of metal = 5.78 g/mL

volume = final volume of water - initial volume of water

volume = 24.7 - 22.3 = 2.4 mL

We have

mass = 5.78 × 2.4 = 13.872

We have the final answer as

Hope this helps you

lol for the pointsss
