Astudent needs to conduct a reaction that combines chemicals a and b to synthesize product ab. if we write this as a chemical equation it looks like: a+b→ab if this student combines 100 molecules of a and 100 molecules of b, the student obtains 100 molecules of ab. how many molecules of a would this student need to make 5000 molecules of ab? (assume the student had enough of molecule b to make 5000 molecules of ab.)

100 molecules of A would this student need to make 5000 molecules of AB.

Explanation:

A + B → AB

100 A molecules reacts with 100 B molecules to give 100 AB molecules.

This can also be written as , 100 molecules of AB are obtained from 100 molecules of A.

Then 5000 molecules of AB are obtained from:

molecules of A

So, in order to obtain 100 molecules of AB 100 molecules of A are needed.
