Question

What is the limiting reactant if 70.0 g of C7H6O3 and 80.0 g of C4H6O3 react?

Answer 1

I think because the water

Answer 2

C7H6O3 is the limiting reactant

Step-by-step explanation:

Given:

Mass of C7H6O3 = 70.0 g

Mass of C4H6O3 = 80.0 g

To determine:

The identity of the limiting reactant

Step-by-step explanation:

In a chemical reaction, limiting reagent is the reactant which directly influences the amount of product formed. This is identified by calculating the number of moles of each reactant, the reactant with lower moles is the limiting reactant

`Moles = (Mass)/(Molar Mass)`

Molar Mass of C7H6O3 = 126 g/mol

`Moles\ C7H6O3 = (70.0)/(138) = 0.507 moles`

Molar Mass of C4H6O3 = 102 g/mol

`Moles\ C4H6O3 = (80.0)/(102) = 0.784 moles`

Since moles if C7H6O3 is less than C4H6O3, the former is the limiting reactant
