The Daltons to Moles Calculator is a useful tool designed to convert atomic mass, expressed in Daltons (Da), into moles. Scientists, chemists, and students frequently use this calculation when working with molecules and atomic structures in chemistry and biochemistry.
A Dalton (Da) is a unit of mass that represents the mass of a single atomic or molecular entity. It is numerically equivalent to the unified atomic mass unit (u). Since the molar mass of a substance (in grams per mole) is numerically equal to its molecular weight in Daltons, this calculator simplifies conversions for research, lab work, and academic calculations.
This tool is particularly helpful in molecular biology and biochemistry when analyzing large macromolecules such as proteins, nucleotides, and enzymes. It ensures precision in calculating the number of moles based on mass and molecular weight.
Formula for Daltons To Moles Calculator
The Dalton to Moles conversion follows a straightforward formula:
Moles = Mass in Daltons / Molar Mass (g/mol)
Where:
- Moles is the quantity of substance in moles.
- Mass in Daltons is the total atomic or molecular mass in Daltons.
- Molar Mass is the molecular weight of the substance in grams per mole (g/mol).
Since the molar mass is numerically equal to the molecular weight in Daltons (g/mol = Da), the calculation becomes direct and easy to perform.
Dalton to Moles Conversion Table
To make the conversion easier, here is a table showing commonly used molecular weights and their mole equivalents.
| Mass in Daltons (Da) | Molar Mass (g/mol) | Moles |
|---|---|---|
| 1,000 Da | 1,000 g/mol | 1.0 × 10⁻³ |
| 10,000 Da | 10,000 g/mol | 1.0 × 10⁻³ |
| 50,000 Da | 50,000 g/mol | 1.0 × 10⁻³ |
| 100,000 Da | 100,000 g/mol | 1.0 × 10⁻³ |
| 500,000 Da | 500,000 g/mol | 1.0 × 10⁻³ |
| 1,000,000 Da (1 MDa) | 1,000,000 g/mol | 1.0 × 10⁻³ |
This table helps users quickly determine mole values without manually calculating each time.
Example of Daltons To Moles Calculator
Let's say you have a protein with a molecular weight of 50,000 Daltons, and you want to find out how many moles it represents.
Using the formula:
Moles = 50,000 Da / 50,000 g/mol
Moles = 1.0 × 10⁻³ moles
This means that 50,000 Daltons of this protein corresponds to 1.0 × 10⁻³ moles.
