The chemical formula for potassium dichromate is K2Cr2O7. In one formula unit of K2Cr2O7 there are 7 oxygen atoms. Thus in 2 mol of K2Cr2O7 there would be 7(2)=14mol of oxygen atoms.
The formula for potassium dichromate is KËÃCrËÃOËÈ. How many grams of oxygen will be in 2 moles of potassium dichromate?
224 grams of oxygen are in 2 moles of potassium dichromate.
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
224 g are in two moles of potassium dichromate.
In one mole of potassium dichromate, there seven moles of oxygen. This means in two moles of K2Cr2O7, there are 14 moles of O, or 7 Moles of O2, which equals 224 grams.
1,2 kg of potassium dichromate are equivalent to 4,079 moles.
Structure for this is K2Cr2O7. there are 14 moles of O in 2 moles.
The answer is 224,24 g oxygen.
The answer is 224,141 grams oxygen.
2 KClO3 ----> 2KCl + 3O2 So 2 moles of Potassium Chlorate produces 3 moles of oxygen molecules or 6 moles of oxygen atoms. 3 moles of Potassium chlorate would thus produce 4.5 moles of oxygen molecules or 9 moles of oxygen atoms.
8,55 moles of oxygen are produced.
The answer is 1 mole potassium chlorate.
Four moles of potassium chlorate are needed.
We need 3 moles of potassium perchlorate.
The chemical reactin is:2 KClO3 = 2 KCl + 3 O24 moles of potassium chlorate produce 6 moles oxygen.
12 moles KClO3 (3 moles O/1 mole KClO3) = 36 moles of oxygen.
The anwer is 0,061 moles of oxygen.

Potassium chlorate = KClO3Decompostion: 2KClO3 ==> 3O2 + 2KCl7.5 moles KClO3 x 3 mole O2/2 moles KClO3 = 11.25 moles O2
3 alcohol : 2 dichromate
The reaction is:2 KClO3 = 2 KCl + 3 O238,4 moles of oxygen are produced.
2KClO3 --> 2KCl + 3O2For every 3 moles of oxygen gas produced, 2 moles of potassium chlorate are used.6 moles O2 * (2 moles KClO3 reacted / 3 moles O2 produced) = 4 moles KClO3
A balanced equation for the reaction is 2 KClO3 -> 2 KCl + 3 O2. Therefore, each mole of potassium chlorate produces 3/2 moles of oxygen, and 1.2 moles of potassium chlorate produces (3/2)1.2 or 1.8 moles of oxygen.
Dichromate is Cr2O7^2- so it has 7 oxygen atoms in one molecule
In 48 g of potassium are 1,228 moles.
