A chemist wants to make 1.5 L of 0.5M HBr by diluting a 6.OM HBr solution. Hon many liters of that solution should be used?

Answer : The volume of HBr solution used should be, 0.125 L.

Explanation :

Formula used :

where,

are the molarity and volume of HBr solution.

are the molarity and volume of diluted HBr solution.

We are given:

Putting values in above equation, we get:

Therefore, the volume of HBr solution used should be, 0.125 L.

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.
