## How many moles are in KClO3?

​According to the equation 2 moles of KClO3 gives 3 moles of oxygen (O2). To obtain 6 moles of oxygen we multiply chemical equation by 2. Hence, 4 moles of KClO3 are required to give 6 moles of oxygen.

## How do I calculate molecular weight?

Sample Molecular Weight Calculation

Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen’s is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.

## How many grams of KClO3 must be?

M = Molar mass of the compound. As we can see that 3 moles of O2were produced from decomposition of 2 moles of KClO3which means 96g of O2were produced from decomposition of 244g of KClO3. -Therefore, 24.4 grams of potassium chlorate should be decomposed to obtain 9.6 grams of oxygen.

## What is the molar mass of 2kclo3?

The molar mass and molecular weight of 2KCIO3 is 245.099.

## How many moles of KClO3 must completely react?

You’d need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen.

## What is moles to grams?

In order to convert the moles of a substance to grams, you will need to multiply the mole value of the substance by its molar mass.
