The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
Atomic mass of sodium is 23. The atomic mass of oxygen is 16. Therefore the molecular mass of sodium oxide is 23x2+16=62u.The atomic mass of oxygen is 16. Atomic mass of sodium is 23. Therefore the molecular mass of the given compound is 62 grams per mole.
The molecular mass of sodium chloride (NaCl) can be calculated by adding the atomic masses of sodium (Na) and chlorine (Cl). Sodium has an atomic mass of approximately 22.99 g/mol, and chlorine has an atomic mass of about 35.45 g/mol. Therefore, the molecular mass of NaCl is approximately 58.44 g/mol.
The molecular mass of sodium thiosulfate heptahydrate is 248,18 g.
Sodium hydroxide has the formula NaOH and it contains three atoms, one each of Sodium, Hydrogen and Oxygen.
The molecular weight of sodium hydroxide is 40g/mol. To get the amount of moles, you have to divide the weight by molecular mass. 12g / 40 is 0.3 moles. This is 300 millimoles.
The a.m.u. is defined as the fraction of 1/12 of an atom of the carbon-12 isotope. The value is pretty nearer to the mass of a hydrogen atom. Therefore, in every compound, the gram molecular weight is numerically equal to the molecular mass in atomic mass units. Therefore the gram molecular weight of NaOH is 40 g/mol.
To find the grams of sodium hydroxide in 0.150 mol, first calculate the molar mass of sodium hydroxide, which is approximately 40 g/mol. Then, multiply the molar mass by the number of moles: 40 g/mol x 0.150 mol = 6 grams of sodium hydroxide.
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)
Sodium carbonate has sodium, carbon and oxygen in it, and the molecular formula is NaCO. Sodium hydroxide is consists of the elements sodium, oxygen and hydrogen and it has the molecular formula NaOH. One of the common features of both these compounds are being alkali in aqueous medium.
The molecular mass of sodium chloride is 58,44 (rounded).
The molecular mass of sodium nitrate is 84,9947.
Atomic mass of sodium is 23. The atomic mass of oxygen is 16. Therefore the molecular mass of sodium oxide is 23x2+16=62u.The atomic mass of oxygen is 16. Atomic mass of sodium is 23. Therefore the molecular mass of the given compound is 62 grams per mole.
The molecular mass of sodium chloride is 58,439 769 28.
The molecular mass of sodium chloride is 58,439 769 28.
To find the number of moles in 4.75g of sodium hydroxide, you first need to determine the molar mass of sodium hydroxide (NaOH), which is about 40g/mol. Then divide the given mass (4.75g) by the molar mass to obtain the number of moles: 4.75g / 40g/mol = 0.119 moles of NaOH.
The molecular equation for iron chloride and sodium hydroxide is: FeCl3 + 3NaOH -> Fe(OH)3 + 3NaCl.
