Question

1. in a chemical reaction, if you have 2.5 moles of reactant a and the balanced equation shows a 1:2 ratio between reactant a and product b, how many moles of product b can be produced theoretically? 1.25 moles 2.5 moles 5.0 moles 7.5 moles clear all

Explanation:

Step1: Define mole ratio

Mole ratio of A:B = $1:2$, so $\frac{\text{Moles of A}}{\text{Moles of B}} = \frac{1}{2}$

Step2: Rearrange to solve for B

$\text{Moles of B} = 2 \times \text{Moles of A}$

Step3: Substitute given value

$\text{Moles of B} = 2 \times 2.5$

Answer:

5.0 moles
