# What is the mole ratio of Fe?

Contents

The molar mass of Fe is 55.845 grams (1 mole Fe = 55.845 grams Fe). The molar mass of O2 is 2 x 16.00 or 32.00 grams (1 mole O2 = 32.00 grams O2). The mass of a mole of Fe2O3 is (2 x Fe) + (3 x Oxygen) = (2 x 55.845) + (3 x 16.00) = 159.69 grams (1 mole of Fe2O3 = 159.69 grams Fe2O3).

## What is the mole mole ratio of KClO3 o2?

You’d need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you’ll always produce 3/2 times more moles of the latter.

## What is the mole ratio of Al to Al2O3?

3.7 mol Al2O3 x 4 mol Al = 7.4 mol Al 2 mol Al2O3 Done using the mole ratio’s as conversion factors with dimensional analysis.

## What is the mole ratio of hydrogen to ammonia?

The ‘Moles” are the coefficients of the molecules in the reaction equation. In this equation the coefficient of hydrogen is ‘3’ and the coefficient of ammonia is ‘2’. So, the ratio of hydrogen to ammonia is 3:2.

## What is the maximum number of moles of AlCl3 that can be produced from 5.0 mol Al and 6.0 mol Cl2?

Multiply the moles of each reactant by the mole ratio between the reactant and AlCl3 in the balanced equation, so that the moles of each reactant cancel, leaving moles of AlCl3. Cl2 is the limiting reactant, therefore a maximum of 5.3 mol AlCl3 can be produced.
