Asubstance has an empirical formula of ch2br and a molar mass of 188 g mol-1 . what is the molecular formula of the compound?

Answer : The molecular of the compound is,

Explanation :

The Empirical formula =

The empirical formula weight = 1(12) + 2(1) + 1(80) = 94 gram/eq

Now we have to calculate the molecular formula of the compound.

Formula used :

where,

n = valency factor

Now put all the given values in this formula, we get:

Molecular formula =

Therefore, the molecular of the compound is,

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.
