Mass vs Number of Moles
公式
## How to Convert Moles to Grams ### Formula **mass (g) = moles × molar mass (g/mol)** Multiply the number of moles by the molar mass to get grams.
计算示例
Convert 2 moles of water (Mw = 18.015 g/mol) to grams.
- 01mass = moles × Mw
- 02mass = 2 × 18.015
- 03mass = 36.03 g
常见问题
Why do we need molar mass to convert?
Moles count particles while grams measure mass. Molar mass is the bridge: grams per mole.
Is molar mass the same as molecular weight?
Numerically yes. Molar mass has units of g/mol; molecular weight is in atomic mass units (amu).
How do I find molar mass of a compound?
Sum the atomic masses of all atoms in the molecular formula using values from the periodic table.
