So, our mole ratio of potassium chlorate to oxygen is 2:3 .
What is the experimental ratio of KCl to oxygen?
Determine the mass of the crucible, contents, and cover. Place the crucible on the tripod, place the cover in place, and heat very gently for 2 minutes.
|Mass of empty crucible and cover||22.21 g|
|Mass of potassium chloride produced||1.23 g|
|Mass of oxygen driven off||0.74 g|
|Experimental percentage of oxygen in KClO3||37.6 %|
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).
How many moles of O2 are obtained from one mole of KClO3?
1 mole of KCLlO3 * (3moles KClO3/2moles O2) = 1.5 moles of O2.
What is the mole ratio of KClO3 to 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 Fe3O4?
What is the mole ratio of Fe3O4 to Fe? A- 1:3.
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?
We also see there are 2 moles of Fe2O3.
So their ratio is Fe : Fe2O3 = 4 : 2. The mole ratio between Fe and Fe2O3 is 2 : 1.
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.
What is the mole ratio of NaOH to Al OH 3?
The molar ratios of NaOH to Al(OH)3 are 3 to 1. Therefore, 2.3 moles of NaOH would produce (1/3)*(2.3) moles of Al(OH)3.
What are the 4 types of stoichiometry problems?
4 types of stoichiometry problems
- Mole – mole.
- Mole – mass.
- Mass – mole.
- Mass – mass.
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 many grams are in 1 mole of KCl?
One mol of KCl is equal to 74.6 grams (from the periodic chart, the gram-atomic mass of potassium is 39.0 and that of chlorine is 35.5.
What is the mole ratio of hydrogen to ammonia?
So, the ratio of hydrogen to ammonia is 3:2.
What is the mole ratio of pcl3 to pcl5?
Answer : The mole ratio of to is 1 : 1 ratio.
