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 Fe2O3 and Fe?
The mole ratio between Fe and Fe2O3 is 2 : 1.
What is the mole iron oxygen ratio?
A second example: Iron combines with oxygen to form a compound called “ferrous oxide”. The ratio of mass of oxygen to iron is 0.2865.
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.
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.
What is the mole ratio of CO2 to O2?
The chemical formula tells us the mole ratio. CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms. 1 C12H22O11 molecule: 12 O2 molecules : 12 CO2 molecules : 11 H2O molecules.
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 Ni to nii2?
Notice that you have a 3:1 mole ratio between nickel(II) chloride and nickel(II) phosphate.
What is the mole 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 of Al to Al2O3?
3.7 mol Al2O3 x 4 mol Al = 7.4 mol Al 2 mol Al2O3 Done using the mole ratio’s as conversion factors with dimensional analysis.
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 maximum number of moles of AlCl3 that can be produced from 5.0 mol Al and 6.0 mol Cl2?
Multiply the moles of each reactant by the mole ratio between the reactant and AlCl3 in the balanced equation, so that the moles of each reactant cancel, leaving moles of AlCl3. Cl2 is the limiting reactant, therefore a maximum of 5.3 mol AlCl3 can be produced.
What is the mole ratio of PbO2 to water quizlet?
Terms in this set (16) A car battery produces electrical energy with the following chemical reaction. What is the mole ratio of PbO2 to water? PbOes001-2.
How many moles of aluminum are needed to react completely with 1.2 moles FeO?
of moles of Al are needed to react completely with 1.2 mol of FeO = (2 mol)(1.2 mol)/(3 mol) = 0.8 mol.
