1. What is g/mol to AMU Conversion?

The conversion between grams per mole (g/mol) and atomic mass units (AMU) is based on the definition that 1 mole of a substance contains Avogadro's number of particles (6.022×10²³), and 1 AMU is defined as 1/12th the mass of a carbon-12 atom.

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Explanation: By definition, the molar mass of a substance in g/mol is numerically equal to its atomic or molecular mass in AMU.

3. Importance of the Conversion

Details: This conversion is fundamental in chemistry for relating macroscopic measurements (grams) to atomic-scale masses (AMU). It's essential for stoichiometric calculations and molecular mass determinations.

4. Using the Calculator

Tips: Simply enter the value in g/mol to get the equivalent in AMU. The value must be positive.

5. Frequently Asked Questions (FAQ)

Q1: Why are g/mol and AMU numerically equal?
A: This is by definition - the atomic mass unit scale was designed so that 1 mole of particles with mass 1 AMU each would weigh exactly 1 gram.

Q2: Is this conversion exact?
A: Yes, this is an exact conversion based on the definitions of the mole and AMU in the SI system.

Q3: Does this work for molecular weights?
A: Yes, the same conversion applies to both atomic masses and molecular weights.

Q4: What's the difference between AMU and Da?
A: The dalton (Da) is another name for the atomic mass unit (AMU). They are identical units.

Q5: How precise is this conversion?
A: The conversion is mathematically exact, though actual measurements of atomic masses have experimental uncertainties.
