## How many moles of O2 are in KClO3?

So, **6 moles** of Oxygen Gas O2 has been given to you. To calculate the number of moles for potassium chlorate KClO3 , use the mole ratio.

## How many moles of O2 can be produced from 12 moles KClO3?

How many moles of O2 can be produced by letting 12.00 moles of KClO3 react? The KClO3 / O2 molar ratio is 2/3. 2 mol KClO3 / 3 mol. O2 = 12.00 mol KClO3 / x = **18.00 mol**.

## How many grams of O2 are produced if 5 moles of KClO3 is used?

122.55 g of KClO3 yields 3*32 g of O2. 1 g of KClO3 would yield 0.783353733 g of O2. Thus 5 g of KClO3 would yield 5*0.783353733 g of O2 or **4.0 g O2**.

## 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 many moles of KClO3 must completely react?

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

## How many moles of O2 are produced from 3.0 moles of KCLO3?

The balanced equation tells us that we get 3 moles of O_{2} for every 2 moles of KClO_{3}. (3/2)*(3.0) moles O_{2}, or **4.5 moles** of O_{2}. Kaitlyn G.

## How many moles of ammonia can be produced from 8 moles of nitrogen gas?

6 * 2/3 moles of ammonia must be produced. Therefore **4 moles** of ammonia can be produced.

## How many moles of O2 will be obtained by decomposing 3.5 moles KClO3?

Now as you see, the yield of the reaction is 85% which means that out of the number of moles of the products to be given out, only 80% is obtained. In order to obtain 3.50 moles of O2 , which is 85% of the no. of moles which ought to be obtained. Therefore, **2.75 moles** of KCLO3 is required.
