Actually massnumbers are only given to (isotopes) of elements.
If you want to know the molecular mass, molar mass one should add up all atomic masses (not the same as 'mass numbers') of that molecule:
Na=22.98977, O=16.00, H=1.008, so the molar mass of NaOHis 39.998 = 40.00 g/mol.
(Note that atomic masses are not exact, but rounded numbers, while mass numbers are exact quantities (whole numbers): Na=23, O=16, 17, 18 and H=1)
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
the mass number of sodium is 23
Sodium hydroxide (chemical composition NaOH) has an atomic mass of 40 amu which is also 40 grams/mole
The term NaOH represents the chemical compound sodium hydroxide. It is mainly used in the form of sodium hydroxide solution. Solid sodium hydroxide is an essential component of drain cleaners.
It is 25 moles of Sodium Hydroxide (;
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
the molar mass of sodium hydroxide is 40g/mol mike
The chemical name is Sodium Hydroxide. It is made of Na+ ions and OH- ions.
No, the mass is conserved.
39.997 g mol-1
First, you must either find or be provided with a known mass of sodium hydroxide and a volumetric vessel. You must also know the molecular mass of sodium hydroxide, which is about 40.00. If the volume of sodium is sufficient, you can complete the preparation by determining the volume of the volume of the vessel in litres, multiply this volume by twice the molecular mass of sodium hydroxide, and dissolve the resulting mass in the known volume.
the mass number of sodium is 23
Sodium hydroxide has the formula NaOH and it contains three atoms, one each of Sodium, Hydrogen and Oxygen.
Sodium hydroxide (chemical composition NaOH) has an atomic mass of 40 amu which is also 40 grams/mole
The gram molecular formula unit mass of sodium hydroxide is 40.00. Therefore,4.75 g constitutes 4.75/40.00 or 1.19 X 10-1 mole, to the justified number of significant digits.
Sodium hydroxide is basic.
