Molar mass of iron is 56g.
Given mass of iron= 112g
No. of moles = Given mass/Molar Mass
=> 112g/56g= 2 moles
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
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
Zn + 2HCl ---> H2 + ZnCl2n = 0.112mw = 65.39g = 7.35From these values (they are for the zinc), you can see that only .112 mol of Zn reacted.To find the number of moles of HCl, we use n = cV.n = 1.2 x 0.5= 0.6 x 2 mols= 1.2 mol HCl.From this we can see that zinc is the limiting reagent and that 0.112 mol of H2 gas was produced.g = mw x ng = 2.016 x 0.112= 0.225792 grams.
112 degrees Fahrenheit = 44.44 degrees Celsius
Generally, any element with a lower atomic number.
To find the number of moles in 15.8 grams of C6H12O6, first calculate the molar mass of C6H12O6 which is 180 g/mol (126 + 112 + 16*6). Then divide the given mass by the molar mass to get the number of moles. In this case, 15.8g / 180 g/mol = 0.088 moles.
To find the molarity, first calculate the molar mass of KOH (56.11 g/mol for KOH). Next, divide the given mass of KOH (112 g) by its molar mass to get the number of moles. Finally, divide the moles of KOH by the volume of the solution in liters (2.00 L) to get the molarity. The molarity of the solution is 28.0 M.
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.
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
112/32 moles for every mole of sulfur there are 32g
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
54 + 58 = 112
112 is composite.
The recently named element copernicuim has the number 112.

At Standard Temperature and Pressure (STP), the volume of 1 mole of gas is 22.4 L. Therefore, if the balloon holds 5.00 moles of gas at STP, the volume would be 5.00 moles x 22.4 L/mole = 112 L.
97.44 is 112% of 87
