# What does a mole ratio tell you?

## Why are mole ratios important?

The mole ratio is the proportion of number of moles of any two chemical entities involved in a compound or a chemical reaction. Studying the mole ratio is important to calculate the reaction yield, determine the stoichiometry and monitor the reaction kinetics.

## What does molar ratio mean?

The molar ratios identify how many moles of product are formed from a certain amount of reactant, as well as the number of moles of a reactant needed to completely react with a certain amount of another reactant.

## How do I calculate moles?

How to find moles?

1. Measure the weight of your substance.
2. Use a periodic table to find its atomic or molecular mass.
3. Divide the weight by the atomic or molecular mass.
4. Check your results with Omni Calculator.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

## How do you find the simplest molar ratio?

To find the simplest whole number ratio, divide each number by the smallest number of moles:

1. Sn: 0.664 / 0.664 = 1.00.
2. O: 1.33 / 0.664 = 2.00.

## Can you reduce mole ratios?

Write the molar ratios for (a) NH3 to N2 and (b) H2O to O2. Note that both ratios can be reduced. Eventually, ratios like the above will be used in calculations. You may use the unreduced ratio or the reduced ratio in the actual calculation.
