Atomic number is a property of an atom (An Element) and not a chemical compound. Sodium chloride is a compound and thus it can not have any atomic number.
Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.
The most common calcium isotope, calcium-40, has 20 neutrons.
At No(F) + At No(Na) = 20.At No of Calcium = 20.
the % hydrate of calcium sulfate is 20.9%
To calculate the number of moles in a sample, divide the mass of the sample by the molar mass of the compound. The molar mass of calcium sulfate is calculated by adding the atomic masses of calcium, sulfur, and four oxygen atoms: Ca = 40.08 g/mol S = 32.06 g/mol O = 16.00 g/mol Molar mass of calcium sulfate = (40.08 g/mol) + (32.06 g/mol) + (4 × 16.00 g/mol) = 136.14 g/mol Now we can calculate the number of moles in 54.0 grams of calcium sulfate: Number of moles = mass (g) / molar mass (g/mol) = 54.0 g / 136.14 g/mol = 0.397 moles (rounded to three decimal places)
The chemical formula for Calcium Sulfate is CaSO4
