1. What is the Relationship Between g/mol and Daltons?

The gram per mole (g/mol) and Dalton (Da) are equivalent units used to express molecular mass. One Dalton is defined as 1/12 the mass of a carbon-12 atom, which is exactly 1 g/mol by definition in the atomic mass unit system.

2. How Does the Conversion Work?

The conversion formula is straightforward:

This means the numerical value remains the same when converting between these units.

3. Importance of Molecular Weight Units

Details: Molecular weight is crucial in chemistry and biochemistry for stoichiometric calculations, determining concentrations, and understanding molecular properties. Both g/mol and Daltons are widely used in scientific literature.

4. Using the Calculator

Tips: Enter the molecular weight in g/mol, and the calculator will provide the equivalent value in Daltons. The conversion is direct with no change in numerical value.

5. Frequently Asked Questions (FAQ)

Q1: Are g/mol and Daltons exactly the same?
A: Yes, by definition, 1 g/mol equals exactly 1 Dalton. They are different names for the same unit of molecular mass.

Q2: When should I use g/mol vs Daltons?
A: g/mol is more common in general chemistry, while Daltons are frequently used in biochemistry and molecular biology, especially for proteins and large biomolecules.

Q3: What is the relationship to atomic mass units (amu)?
A: Dalton and atomic mass unit (amu) are essentially the same measurement. 1 Da = 1 amu = 1 g/mol.

Q4: How precise is this conversion?
A: The conversion is exact with no approximation needed, as these units are defined to be equivalent.

Q5: Can I use this for kilodaltons (kDa)?
A: Yes, simply multiply the result by 1000 or move the decimal point three places. For example, 65,000 g/mol = 65,000 Da = 65 kDa.
