How many moles are in CuSO4 5H2O?
How many moles are in CuSO4 5H2O?
As the formula indicates, water forms a definite percentage of the weight of any hydrate. For example, the weight of a mole of CuSO4•5H2O is 250 grams (this is the molar mass of CuSO4•5H2O). A mole of CuSO4•5H2O contains 5 moles of water (which corresponds to 90 grams of water) as part of its structure.
How many moles are in copper II sulfate?
1 moles
How do you find the molar mass of CuSO4 5H2O?
Number of moles in 24.9 g of CuSO4. 5H2O: number of moles = mass / molar mass = 24.9 / 249.72 = 0.100 mol. Note that the question gave the mass as 24.9 g – three significant figures. The answer reflects this.
How do you find the moles of copper sulfate?
So copper (II) sulfate pentahydrate has a molar mass of: (63.546 x 1) + (32.066 x 1) + (15.9994 x 4) + (1.0079 x 10) + (15.9994 x 5) = 249.6856 g/mol.
What is the mass of two moles of calcium chloride?
Since calcium chloride is a solid, it would be convenient to use a balance to measure the mass that is needed. The molar mass of CaCl2 is 110.98 g/mol.
What does CuSO4 5H2O mean?

What is the mass in grams of 1 mole of hydrated copper II sulfate?
The CuSO4·5H2O (249.7 g/mol) will weigh the most and the CuSO4 (159.6 g/mol) will weigh the least.
What is difference between Formula mass and molecular mass?
The formula mass of a substance is the sum of the average atomic masses of each atom represented in the chemical formula and is expressed in atomic mass units. The formula mass of a covalent compound is also called the molecular mass. The mass in grams of 1 mole of substance is its molar mass.
What is average molecular mass?
The number average molecular weight is the total weight of the sample divided by the number of molecules in the sample. The Average Molecular Weight of a mixture is computed from the molar composition and the molecular weight.
What are the uses of medicine?
