From looking at our balanced equation, we know that 2 moles of potassium chlorate produces 3 moles of oxygen, or O2 . So, our mole ratio of potassium chlorate to oxygen is 2:3 .
What is the mole ratio of KClO3 O2?
You’d need 33.3 moles of potassium chlorate, KClO3 , to produce that much oxygen. Notice that you have a 2:3. mole ratio between potassium chlorate and oxygen gas, which means that, regardless of how many moles of the former react, you’ll always produce 3/2 times more moles of the latter.
What is the mole ratio for KClO3 KCL?
Look at the mole ratio you have between potassium chlorate and potassium chloride; what you will see is that every 2 moles of potassium chlorate will produce 2 moles of potassium chloride, i.e. you have a 1:1 mole ratio between the two compounds.
What is the mole ratio of O2?
The molar mass of Fe is 55.845 grams (1 mole Fe = 55.845 grams Fe). The molar mass of O2 is 2 x 16.00 or 32.00 grams (1 mole O2 = 32.00 grams O2). The mass of a mole of Fe2O3 is (2 x Fe) + (3 x Oxygen) = (2 x 55.845) + (3 x 16.00) = 159.69 grams (1 mole of Fe2O3 = 159.69 grams Fe2O3).
What is the mole ratio of pcl3 to pcl5?
Answer : The mole ratio of to is 1 : 1 ratio.
What is the mole ratio of Fe3O4 to FE?
2) In the case of Fe3O4 and Fe, the chemical equation is: Fe+H2O → Fe3O4+H2. 4) From that the mole ratios are: 3 mol Fe : 4 mol 4H2O : 1 mol Fe3O4 : 4 mol H2.
What is the mole ratio?
A mole ratio is a conversion factor that relates the amounts in moles of any two substances in a chemical reaction. The numbers in a conversion factor come from the coefficients of the balanced chemical equation.
How many grams of KClO3 are needed to make 3.50 moles KCl?
Answer: 484.925 grams KClO3. Explanation: Given 3.50 moles of KCl as the target amount in the problem, used the coefficient of the balanced chemical reaction involved to determine the number of moles of potassium perchlorate needed.
What is the mole ratio of hydrogen to ammonia?
The ‘Moles” are the coefficients of the molecules in the reaction equation. In this equation the coefficient of hydrogen is ‘3’ and the coefficient of ammonia is ‘2’. So, the ratio of hydrogen to ammonia is 3:2.
What is the mole ratio of Fe2O3?
What is the mole ratio of oxygen to pentane?
Answer: The mole ratio of oxygen to pentane for the combustion of pentane is 8 : 1.
What is the mole ratio of Fe2O3 to FE?
The mole ratio between Fe and Fe2O3 is 2 : 1.
Do you reduce mole ratios?
The molar ratio can be constructed using any two compounds in the reaction, be they reactants or products. Write the molar ratios for (a) O2 to SO3 and (b) SO2 to SO3. … Note that both ratios can be reduced.
How do I calculate moles?
- First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
- For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
