Calculate the percentage of limestone that dissolved from each solution. Start by subtracting the final mass from the initial mass. Divide that number by the initial mass. Then multiply the result by 100 to make it a percent. Use this formula: % dissolved= initial mass- final mass/ initial mass x 100

ORIGINAL: 0% Acid 33% Acid 66% Acid 100% Acid

Initial Mass (g) 10.0 10.1 10.0 9.9

Final Mass (g) 10.0 10.0 9.8 9.5

Record the percentage of limestone dissolved in each acid concentration.

How do we find the answer?

Vander waals forces are inter molecular bonds that exist within molecules of the same substance. a water molecule is made up of oxygen and hydrogen atoms which share electrons between each other. the vander waals forces are forces that exist between multitude of different  molecules of water. dipole dipole forces is the type of vander waals force that exist in water. the oxygen atom which is more electronegative pulls the shared electron closer to itself thus generating a partial negative charge while the hydrogen acquire a partial positive charge. these two different charges causes attraction to occur in water molecules.
