8 g NaOH x 1 mole NaOH/40 g = 0.2 moles NaOH
0.2 mol
The mass is 467,52 g.
0,666 moles
We need 8 moles potassium chloride.
The answer is 7,18.10e-10 moles.
0.2 mol
The molar mass of sodium is 22.99 g/mol. Therefore, the mass of 8 moles of sodium would be 8 moles x 22.99 g/mol = 183.92 g.
To find the number of moles of NaOH in 8 g, first calculate the molar mass of NaOH (sodium hydroxide) which is approximately 40 g/mol (sodium - 23 g/mol, oxygen - 16 g/mol, hydrogen - 1 g/mol). Then, divide the given mass (8 g) by the molar mass to get the number of moles. So, 8 g / 40 g/mol = 0.2 moles of NaOH.
The molar mass of sodium is 22.99 g/mol. To find the mass of 8 moles of sodium atoms, you would multiply the molar mass by the number of moles: 22.99 g/mol * 8 mol = 183.92 g. Therefore, the mass of 8 moles of sodium atoms is 183.92 grams.
The molar mass of sodium (Na) is 22.99 g/mol. Therefore, the mass of 8 moles of sodium atoms would be 8 moles x 22.99 g/mol = 183.92 grams.
The mass is 467,52 g.
Sodium chloride has a molar mass of about 58.5 g/mol. So multiply 8 moles by molar mass to get about 468 grams.
Im pretty sure that because sodium hydroxide is a compound, it doesnt have an atomic number, as it is more than one atom.. maybe you should rephrase your question?
1. Sodium hydroxide 2. Pottassium hydroxide 3. Ammonium hydroxide 4. Calcium hydroxide 5. First base 6. Second base 7. Third base 8. The base of a triangular pyramid.
8gNa*(1mol/22.989770)(6.022E23) = 2.09554E23 22.98 is the molar mass of sodium 6.022E23 is avgdros number, which pertains to the amount of molecules in a mole of substance.
Bases comprises of hydroxide ions. The examples of bases are as follows: sodium hydroxide magnesium hydroxide calcium hydroxide lithium hydroxide potassium hydroxide
