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
The molar mass of copper II hydroxide is 97.561 g/mol.
223.1 g/mol
the molar mass of sodium hydroxide is 40g/mol mike
The formula mass of KCl is 75.5 so when 94.375g of it are dissolved in i litre water the solution prepared is 1.25 molar
The molar mass of NaOH is 39.9 g/mol, so if you multiply is by 2.5, you get the answer. 99.75 g/mol
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
Molar mass of the hydroxide anion, OH-, is 17.00734 g/mol
the molar mass of potasium hydroxide is 56 g/mole
CuOH2
the molar mass of sodium hydroxide is 40g/mol mike
Molar mass of barium hydroxide, Ba(OH)2 = 171.3Amount of barium hydroxide = mass of sample / molar mass = 317.0/171.3 = 1.85mol
many other sites say it is zinc, but it is actually copper as the molar mass of a certain metal hydroxide is 97.56. Using the molar mass formula the answer is 63.54 which has a molar mass closer to Copper than zinc.
Formula: Cu(OH)2
Formula: Cu(OH)2
The molar mass of aluminium hyroxide is approximately 78 g/mol.
molar mass is the mass of one mole of a substance. A mole is an amount, refers to Avogadros number which is 6.022 x 1023. a mole of atoms is that many atoms. therefore the molar mass of potassium hydroxide KOH is the mass of that many molecules of KOH. On the periodic table the mass number for each element is molar, so all you need to do is add together the molar mass of each element in the compound. Molar mass of potassium (K) is 39 Molar mass of oxygen (O) is 16 Molar mass of hydrogen (H) is 1 There is one of each of these elements in a molecule of potassium hydroxide therefore the molar mass = 39 + 16 + 1 = 56
The formula mass of KCl is 75.5 so when 94.375g of it are dissolved in i litre water the solution prepared is 1.25 molar
