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 sodium hydroxide is 40g/mol mike
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
To calculate the mass of 2.5 moles of sodium hydroxide (NaOH), you need to know the molar mass of NaOH, which is 40 g/mol. Multiply the number of moles by the molar mass: 2.5 moles x 40 g/mol = 100 grams of sodium hydroxide.
Aluminium hydroxide, Al(OH)3 has molar mass 27.0+3(17.0) = 78.0Amount of Al(OH)3 = 39.0/78.0 = 0.500molThere are 0.5 moles of aluminium hydroxide in a 39.0g pure sample.
To find the number of moles in 40 grams of sodium hydroxide, you first need to calculate the molar mass of NaOH. The molar mass of NaOH is about 40 g/mol. Then, you divide the given mass by the molar mass to get the number of moles. So, 40 grams divided by 40 g/mol is equal to 1 mole of NaOH.
The molar mass of sodium (Na) is 22.99 g/mol, and the molar mass of hydroxide (OH) is 17.01 g/mol. To find the molar mass of sodium hydroxide (NaOH), you can add the molar masses of sodium and hydroxide together, which equals 39.00 g/mol.
the molar mass of potasium hydroxide is 56 g/mole
CuOH2
get the volume of the chemical and the mass and divide the mass by it's volume
Molar mass of the hydroxide anion, OH-, is 17.00734 g/mol
the molar mass of sodium hydroxide is 40g/mol mike
Formula: Cu(OH)2
Formula: Cu(OH)2
The total mass of sodium hydroxide would depend on the amount you have. To calculate it, you would need to know the molar mass of sodium hydroxide (which is 40.00 g/mol) and the number of moles you have, which can be determined by weighing the sample and dividing by the molar mass.
The molar mass of sodium hydroxide (NaOH) is approximately 40 grams/mol. To find the mass of 25 moles of NaOH, you would multiply the number of moles by the molar mass: 25 mol * 40 g/mol = 1000 grams. So, the mass of 25 moles of sodium hydroxide is 1000 grams.
The molar mass of NaOH (sodium hydroxide) is approximately 40 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
