Part 1 You need to find the empirical formula of a compound. This compound has 53.3 g of O, 48.38 g of C and the tiny amount of 8.12 g of H.

Part 2

Based on the empirical formula you found above, what is the molecular formula if the molar mass of the whole compound is 180.15 grams per mole?

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

the dissolution of polymer can be thermodynamically described in 2 steps.
