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 volume of hydrogen at STP is produced from the reaction of 50.0 g of Mg and the equivalent of 75 g of HCl?
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.
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 are contained in 15.8 grams of C6H12O6?
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.
What is the molarity of a solution that contains 112 grams of KOH in 2.00 liters of solution?
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.
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.
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
How many moles in 112g of sulfur?
112/32 moles for every mole of sulfur there are 32g
How many moles are present in 18.4g of CaCl2?

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.

112
What is the volume of a balloon at STP if it holds 5.00 moles of gas?
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.
