One peanut M&amp;M weighs approximately 2.33 g.
Sphinxa [80]

Answer:

There are 23076 peanut M&M's in 53.768 kg of M&M's.

Explanation:

First we <u>convert 53.768 kg into g</u>:

  • 53.768 kg * 1000 = 53768 g

Then we <u>divide the total mass of M&M's by the mass of one peanut M&M,</u> in order to calculate the answer:

  • 53768 g / 2.33 g = 23076

So there are 23076 peanut M&M's in 53.768 kg of M&M's.

What experimental property directly correlates with the strength of the intermolecular forces?
g100num [7]
One experimental property directly related to the strength of intermolecular forces is the boiling point of a substance.

In the liquid state, the intermolecular forces play a large role in the behavior of the substance. If the boiling point is low, this indicates weak forces such as Van der Waal's forces. On the other hand, a high boiling point indicates strong intermolecular forces such as hydrogen bonds.
