How many moles Fe are in a sample of Fe2O3 that contains 100g O?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
How do you convert mole fraction to volume fraction of liquid?
You need the balanced symbol equation for the reaction. The numbers in front of the formulae show the mole ratios. For example, in the thermal decomposition of calcium carbonate: CaCO3 --> CaO + CO2 The equation is balanced. The mole ratio between CaCO3 and CO2 is 1:1 because there is 1 mole of CaCO3 for every mole of CO2
How many equivalents are in the ion 1 mole of Br?
1 equivalent ; im 100% positive that is right *my professor told me lol*
What is the osmolarity of a 0.1 mole sodium chloride solution?
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
If a large balloon contains 224 liters of gas at STP then there is 100 mole of gas in the balloon How many moles of gas are in a balloon that is 560 liters at STP?
0.250 mol
What word means same kind of particles?
A pure substance is one in which 100% of the particles are the same. This is also a homogeneous substance.
How many moles Fe are in a sample of Fe2O3 that contains 100g O?
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
How far can a mole tunnel in?
A mole digs 100 - 150 feet of tunnel each day.

What is the mole fraction of oxygen gas in air?
The mole fraction of Oxygen = 21/100= .21
What is the mole fraction of O2 in the mixture 02?
It is 100%.
How far can a mole tunnel in one night?
it depends on what kind of soil you put a mole in if it is loose soil then you will find pretty small holes if it is hard soil then you will find some pretty large, deep holes in the ground
How many atoms are in 100g of zinc?
100 grams zinc (1 mole Zn/65.41 grams)(6.022 X 1023/1 mole Zn) = 9.21 X 1023 atoms of zinc ------------------------------------
How many equivalents are in the ion 1 mole of Br?
1 equivalent ; im 100% positive that is right *my professor told me lol*
How many moles of fe3o4 are needed to prepare 4.05moles of fe2o3?
Fe3O4 is not a pure compound...it is a mixture of FeO and Fe2O3 Assuming 100% yield in converting to all Fe2O3 4.05 mole x 2/3 = 2.7 mole
How do you find out the mass of 1.25 moles of calcium carbonate?
This question is solved with the help of mole concept . 1 mole of anhydrous calcium carbonate weighs 40+12+48=100 gm . 1.25 mole of similar anhydrous calcium carbonate will be 100* 1.25 = 125 gm
What is the osmolarity of a 0.1 mole sodium chloride solution?
One mole solution of sodium chloride makes 1000 millimole. So 0.1 mole solution of sodium chloride will have 100 millimole in the solution.
