Chemistry Challenge: Mole Ratio Calculation

How many moles of B are required to react with 11.1 moles of A in the reaction below?

In the given reaction, 16.65 moles of B are required to react with 11.1 moles of A. Do you know how this calculation was done?

Answer:

Moles

In the provided reaction equation 2A + 3B = 20, we can see that the mole ratio between A and B is 2:3. This means that for every 2 moles of A, 3 moles of B are required to complete the reaction. To calculate how many moles of B are needed to react with 11.1 moles of A, we can set up a proportion.

Let x represent the unknown number of moles of B. The proportion will look like this:

x mol B / 11.1 mol A = 3 mol B / 2 mol A

Cross multiplying, we get:

2x = 11.1 * 3

2x = 33.3

x = 33.3 / 2

x = 16.65

Therefore, 16.65 moles of B are required to react with 11.1 moles of A in the given reaction. Understanding mole ratios and proportions is crucial in stoichiometry calculations in chemistry.
