This is the chemical formula for acetic acid (the chemical that gives the sharp taste to vinegar):

CH3CO2H

An analytical chemist has determined by measurements that there are 42.7 moles of carbon in a sample of acetic acid.

How many moles of oxygen are in the sample?

Round your answer to 3 significant digits.

The correct answer is:   bri hope this answer was ! : )

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.
