An experiment requires you to use 2.95 x 1023 formula units of sodium phosphide. In order to obtain the correct amount of sodium phosphide, you need to determine the mass, in grams. Which correctly represents the mass in grams of the sodium phosphide?
65.3 g of sodium phosphide
18.6 g of sodium phosphide
49.0 g of sodium phosphide
25.4 g of sodium phosphide

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
