Molecular Weight Calculator (Molar Mass)
It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as “amu”. Also, important in this field is Avogadro’s number (N A) or Avogadro’s constant (6.0221 x 10 23). The term “mole” is defined in that one mole of agram.

Sodium oxalate
Sodium oxalate, or disodium oxalate, is the sodium salt of oxalic acid with the formula Na 2 C 2 O 4.It is a white, crystalline, odorless solid, that decomposes above 290 C. Disodium oxalate can act as a reducing agent, and it may be used as a primary standard for standardizing potassium permanganate (KMnO 4) solutions.

Whats molar mass of N?
 · The molar mass of nitrogen (N) is approximately 14.01 grams per mole of nitrogen atoms. Molar mass is the quantity of an element in grams for every one mole of atoms of that element. Numerically, it’s the same as the element’s atomic mass in units of amu (atomic mass units). A mole, or mol for short, is a quantity of any given thing that is equal to 6.02214 * 10^23 particles. This number, 6

Grams to Moles Calculator

 · How to convert grams to moles: an example Take a look at the example of how to calculate moles from grams. Imagine you have 6 liters of pure water: Find the molar mass of a water molecule (H₂O). It’s ca. 18.015 g/mol. Convert the volume of the water to its mass, assuming that the density of pure water is 998 kg/m³:

 · To remember for getting formula mass of any compound we add the atomic masses of all the atoms not the atomic wt. so atomic mass of Na,C,O,H are 23, 12,16,1 respectively. so formula mass of Na2CO3.10H2O is 2×23+12+3×16+10(2×1+16) =286 amu.
