What is the difference between molecular maas and formula mass?
Molecular mass me sare molecules ke mass ko jod do aur formula mass me sare ions ka....are difference kuch nhi hai dono me bas nam alag hai,.. kam dono ka ek hi hai. i.e, total mass of compound.šš
What is the difference between molecular maas and formula mass?
Fomula mass and molecular mass are two values that express the size of a molecule. Do you know the difference between formula mass and molecular mass?
TheĀ formula massĀ (formula weight) of a molecule is the sum of the atomic weights of the atoms in its empirical formula.
TheĀ molecular massĀ (molecular weight) of a molecule is itsĀ average massĀ as calculated by adding together theĀ atomic weightsĀ of the atoms in the molecular formula.
So, since the definitions differ according to whether you are using the empirical formula or molecular formula for a molecule, it's a good idea to understand the distinction between them.
TheĀ molecular formulaĀ indicates the type and number of atoms in a molecule. TheĀ molecular formulaĀ of glucose is C6H12O6, which indicates that oneĀ molecule of glucoseĀ containsĀ 6 atomsĀ of carbon, 12 atoms of hydrogen, and 6 atoms of oxygen.
TheĀ empirical formulaĀ is also knownĀ as the simplest formula. It is used to indicate the mole ratio of elements present in a compound. TheĀ empirical formulaĀ of glucose would be CH2O.
The formula mass and molecular mass of water (H2O) are one and the same, while the formula and molecular mass of glucose are different from each other. The formula mass (formula weight) of glucose is 30 (either no units or else grams per mole), while the molecular mass (molecular weight) is 180.156 g/mol. Whenever you see a molecular formula where you can divide the subscripts by a whole number (usually 2 or 3), you know to expect the formula mass will be different.
