What is the percent of sulphur in ammonium sulphate?
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.
How many moles are in 72g of Calcium Sulphate?
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.
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
What is the molar mass of copperII hydroxide?
There are 2 forms of Copper(II) Sulphate, each with a different molar mass. * Copper(II) Sulphate Pentahydrate (CuSO4.5H20) This is the more common, blue, crystalline solid. it has a molar mass of: 249.7g mol-1 * Anhydrous Copper(II) Sulphate (CuSO4) This is less common to come across, it is a white powdery solid,and can be obtained by heating the pentahydrated form. Molar mass: 159.6g mol-1
Calculate the mass of 0139 moles of copper?
The molar mass of copper (Cu) is 63.55 g/mol. To calculate the mass of 0.139 moles of copper, you can use the formula: mass = moles × molar mass. Therefore, the mass of 0.139 moles of copper is 8.82 grams.
What is the atomic mass of Alluminium?

Input the equation into a search engine on the internet and see what you come up with.
What is the percent of sulphur in ammonium sulphate?
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.
What is the mass of 5 moles of Potassium Sulphate?
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.
What is the molarity of a solution made by dissolving 23.4g of sodium sulphate in enough water to make up a 125ml solution?
To find the molarity, first calculate the number of moles of sodium sulphate using its molar mass. Sodium sulphate's molar mass is 142.04 g/mol. Next, divide the number of moles by the volume in liters (125 ml = 0.125 L) to get the molarity. This will give you the molarity of the sodium sulphate solution.
How many moles are in 72g of Calcium Sulphate?
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.
Does hydrated copper sulphate increase the mass?
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.
What mass of ammonium sulphate is required to produce 0.5 liters of mole solution?
To determine the mass of ammonium sulfate needed to make a 0.5 M solution: Calculate the molar mass of ammonium sulfate (NH4)2SO4. Use the formula: Mass (g) = Molarity (M) x Volume (L) x Molar mass (g/mol). Plug in the values: Molarity = 0.5 M, Volume = 0.5 L, and Molar mass of (NH4)2SO4. Calculate to find the mass of ammonium sulfate required.
What is the formula mass of ferric sulphate Fe2SO43?
The molar mass of Fe2(SO4)3 is 399,88 g (anhydrous).
