For chemistry you often need to convert moles to grams and grams to moles.
There is a simple relation between these two:
,
where
- mass of the substance in grams
- quantity of the substance in moles
- molar mass of the substance in grams/mole
And the most difficult task here is finding out the molar mass of the substance.
The molar mass is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The molar mass of atoms of an element is given by the standard relative atomic mass of the element multiplied by the molar mass constant, 1 × 10−3 kg/mol = 1 g/mol. The molar mass of a compound is given by the sum of the standard atomic weight (namely, the standard relative atomic mass) of the atoms which form the compound multiplied by the molar mass constant. Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: standard relative atomic masses are dimensionless quantities (i.e., pure numbers), whereas molar masses have units (in this case, grams/mole).
Amu To Grams Formula
Happily, we already have the Molar mass of the substance calculator, which calculates molar mass for a given substance using Periodic table handbook. It is used in the calculator below to parse the chemical compound formula and obtain molar mass.
The calculator below calculates the mass of the substance in grams or the quantity of the substance in moles, depending on the user's input. It also displays the molar mass of the chemical compound and details of its calculation just for reference.
Convert Atomic Mass Unit (amu) to Gram (g), Metric This converter features contemporary units of weight. There is also a special converter for historical units of weight you might want to visit for ancient, medieval and other old units that are no longer used. How to Convert Dalton to Gram. 1 dalton = 1.013E-24 g 1 g = 6.5E+23 dalton. Example: convert 15 dalton to g: 15 dalton = 15 × 1.013E-24 g = 2.02E-23 g. So now 12 amu = 1atom 12 grams = 1 mole of carbon = 6.022.10^23 atoms of carbon (N A Avogadro's number) 1 atom of carbon mass = 12 amu = 12 g /N A Solve it 1amu = 1g/N A You can use any element in place of carbon. Remember mass of 1 atom is in amu and 1 mole is in grams.But value of mass will be same as mentioned in the periodic table.
Note: Always use the upper case for the first character in the element name and the lower case for the second character as in the periodic table. Compare: Co - cobalt and CO - carbon monoxide. Thus, Na3PO4 — correct notation, na3po4/NA3PO4 — incorrect notation.
- Mass = Amu Convert The Mass From Amu To Grams. This problem has been solved! What is the mass, in amu, of 6190 atoms of 27Al? Convert the mass from amu to grams. Previous question Next question.
- Atomic mass unit, unified to Gram conversion. Conversion number between atomic mass unit, unified u; AMU and Gram g is 1.66053904 × 10-24. This means, that atomic mass unit, unified is smaller unit than Gram.
