Molar mass of iron is 56g.
Given mass of iron= 112g
No. of moles = Given mass/Molar Mass
=> 112g/56g= 2 moles

How many moles are present in 18.4g of CaCl2?
By definition, one mole would be the same as the molecular mass. You take the number of moles and multiply it by the molecular mass. So if you have just 1 mole, the number of grams will be the added atomic masses of the elements in the compound.Ca- 40.08Cl- 35.5CaCl- 75.6 grams
What are the elements in the compound Fe2O3?
well Fe is one element and O is another, so there are two, but since there are numbers next to the element symbol, it means there are anumber of those elements combined, such as Fe2 O3 there are two ironmolecules and 3 oxygen molecules combined.. Therefore: 4Fe + 3O2 --> 2Fe2O3
What is unique about element 89-112?
Elements 89-112 are radioactive elements.
Convert 112 degrees Fahrenheit into celsius?
112 degrees Fahrenheit = 44.44 degrees Celsius
What is smaller than the atomic radius of beryllium?
Generally, any element with a lower atomic number.
How many moles in 112g of sulfur?
112/32 moles for every mole of sulfur there are 32g
How many moles are in 500 liters?
You have to say which chemical you have 500 liters of. Moles are not a unit of volume, they refer to a specific number (Avogadro's number) of molecules, and different substances have different molecular sizes.
What is the number such that the sum of 54 and that number is 112?
54 + 58 = 112
Is 112 a composite number?
112 is composite.
Element with atomic number 112?
The recently named element copernicuim has the number 112.
How many moles of ethylene are contained in 112 grams of ethylene?
The formula for Ethylene_ C2H4 STEP 1 Calculate the RMM (Relative molecular mass) of C2H4 C-carbon= 12; H-hydrogen= 1 (check your periodic table people!!!) C*2 + H*4 = 12*2 + 1*4 = 24 + 2 =28 amu/g So... one mole of ethylene has a mass of 28 grams. Number of Moles= Mass / mass of 1 mole ("/" to divide) The mass given is 122g 122g/28g = 4.36 moles Approx 4.4 moles
84 is 75 percent of what number?
112
What is the molarity of a solution that contains 112 grams of KOH in 2.00 liters of solution?
112/56.1056=1.996 so 2.0mole 2 moles/2 liters = 1 M
What is 112 percent of what number is 84?
84/112% = 75
97.44 is 112 percent of what number?
97.44 is 112% of 87
How many grams of c are required to react with 16.5g of fe2o3?
The balanced reaction equation is 2Fe2O3 + 3C = 4Fe + 3CO2 Note the molar ratios are 2:3::4:2 Next calculate the acutal moles of Fe2O3 First using the Periodic Table Calculate the Mr ( Relative molecular mass) of Fe2O3 Fe x 2 = 56 x 2 = 112 O x 3 = 16 x 3 = 48 112 + 48 = 160 mol(Fe2O3) = 16.5 / 160 = 0.103125 Equivlanet to ;2; moles. mol(C) = 0.103125 x 3/2 = 0.1546875 equivalent to '3 moles. Mass(C) = 0.154687 x 12 = 1.85625 g (The Answer!!!!)
What is the volume of a balloon at STP if it holds 5.00 moles of gas?
