Aflask contains 0.180 mol of liquid bromine, br2. determine the number of bromine molecules present in the flask.

The number of molecules of bromine present are

Explanation:

We are given:

Moles of liquid bromine = 0.180 moles

According to mole concept:

1 mole of a compound contains number of molecules.

So, 0.180 moles of liquid bromine will contain = number of molecules.

Hence, the number of molecules of bromine present are

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
