The molar mass of Potassium Sulphate (K2SO4) is 174.26 g/mol. Therefore, the mass of 5 moles of Potassium Sulphate would be 5 moles x 174.26 g/mol = 871.3 grams.
it is because iron is solid and can easily sublimes in aqueous copper sulphate
Mass = weight /gravity Density = Mass / Volume So, if you know the density and the volume, you can calculate the mass. Also, you can measure the mass by measuring the weight. On earth, mass and weight are equal.
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
The formula for calculating mass is mass = density x volume. This formula relates the mass of an object to its density (amount of matter in a given volume) and volume (amount of space an object occupies).
The formula mass of ferric sulphate, Fe2(SO4)3, is calculated by adding the atomic masses of each element: 2(iron) + 3(sulfur) + 12(oxygen). This gives a formula mass of 399.88 g/mol.
The formula of ammonium sulphate is (NH4)2SO4, showing that each formula mass contains one sulphur atom. The formula mass of ammonium sulphate is 132.13, and the gram atomic mass of sulphur is 32.06. Therefore, the percent by mass of sulphur in ammonium sulphate is 100(32.06/132.13) or 24.26, to the justified number of significant digits.
Ferric oxide often refers to iron (III) oxide, which has a chemical formula Fe2O3. The atomic mass of iron (Fe) is 55.85 g/mol, and the atomic mass of oxygen (O) is 16.00 g/mol. Therefore, the molar mass of Fe2O3 is 159.69 g/mol. To calculate the percentage composition of iron (III) oxide, divide the atomic mass of iron by the molar mass of the compound and multiply by 100. So, (2 * 55.85) / 159.69 ≈ 0.698 or 69.8% is the percent of ferric oxide.
The molar mass of ferric ammonium citrate is approximately 270.00 g/mol.
The relative formula mass of iron sulfate is 151.85 g/mol. It is calculated by adding the atomic masses of all the elements in the compound, which are iron (Fe), sulfur (S), and oxygen (O).
The molar mass of Potassium Sulphate (K2SO4) is 174.26 g/mol. Therefore, the mass of 5 moles of Potassium Sulphate would be 5 moles x 174.26 g/mol = 871.3 grams.
The molecular formula of aluminum sulfate is Al2(SO4)3. To calculate the molecular mass, multiply the atomic mass of each element by the number of atoms present in the formula and then add them up. The molecular mass of aluminum sulfate is 342.15 g/mol.
To calculate the number of moles in 72g of Calcium Sulphate (CaSO4), we need to know the molar mass of CaSO4, which is approximately 136.14 g/mol. Then use the formula: moles = mass / molar mass. So, moles = 72g / 136.14 g/mol ≈ 0.53 moles of CaSO4.
When hydrated copper sulfate is heated, it loses water molecules and forms anhydrous copper sulfate, which has a lower mass due to the removal of water. So, the mass would decrease upon heating hydrated copper sulfate.
Ammonium sulfate has the chemical formula (NH4)2SO4. The molar mass of nitrogen is 14.01 g/mol and the molar mass of (NH4)2SO4 is 132.14 g/mol. Therefore, the percentage by mass of nitrogen in ammonium sulfate is (2*14.01)/(132.14) * 100% = 21.2%.
That is the chemical formula. The name would be iron (III) oxide, or ferric oxide in the old system.
The chemical formula for copper sulfate is CuSO4. To determine the number of molecules in a sample of copper sulfate, you would need information about the mass or volume of the sample and perform calculations using Avogadro's number and the molecular weight of copper sulfate.
