How many grams of potassium chlorate would be produced by reacting 500 grams of potassium chlorate with oxygen gas?
Nothing is produced, 500g potassium chlorate will be the same 500 g potassium chlorate after reaction. Actually there is no reaction at all.
If 50 grams of water satured with potassium chlorate 23 Celsius is slowly evaporated to dryness how many grams of the dry salt will be recovered?

How many grams of potassium chlorate are needed to make 250.0ml of a 1.550M potassium chlorate?
(1.550M/liter of solution)(122.55 g/mole of KCLO3) = 190.0 g/liter(190.0 g/ 1000 mL) x 250.0 mL = 47.50 g/250.0 mL
How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose into potassium chloride and oxygen?
You have2KClO3 ==> 2KCl + 3O2 as the balanced equation 25 g KClO3 x 1 mole/123 g = 0.20 moles moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed

He formula for potassium dichromate is KËÃCrËÃOËÈ How many grams of oxygen will be in 2 moles of potassium dichromate?
224 grams of Oxygen will be in 2 moles of Potassium dichromate.
How many grams of potassium chloride are produced if 25 grams of potassium chlorate decompose into potassium chloride and oxygen?
You have2KClO3 ==> 2KCl + 3O2 as the balanced equation 25 g KClO3 x 1 mole/123 g = 0.20 moles moles KCl formed = 0.20 moles KClO3 x 2 moles KCl/2 moles KClO3 = 0.20 moles KCl formed grams KCl = 0.20 moles x 74.5 g/mole = 14.9 g = 15 grams of KCl formed
How many grams of oxygen wil be in two moles of potassium dichromate?
224 g are in two moles of potassium dichromate.
The formula potassium dichromate is K2Cr2O7. How many grams of oxygen will be in 2 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.
How many grams of oxgyen will be in two moles of potassium dichromate?
The answer is 224,24 g oxygen.
When 36.3 g of potassium chlorate is heated 22.1 g of potassium chloride is produced What mass of oxygen is produced?
Equation: 2KClO3 + Cl2 ---> 2KCl + 3O2 + Cl2 1. Solve for the number of moles of KClO3 in 36.3 g. (.2962 molKClO3) 2. Multiply that value by (3/2), from the equation's coefficients. (.4447 molO2) Note: A BCA table could also be used. 3. Solve for the mass of .4447 molO2. 14.2 grams of oxygen would be produced.
