What is this?
A science unit converter handles chemistry and physics units: moles (6.022×10²³ particles), molarity (mol/L), mass (g), and particle count. Uses Avogadro's number for particle conversions. A mole is the SI unit for amount of substance—one mole contains Avogadro's number of particles. Molarity is moles per liter of solution. The converter handles moles to mass (using molar mass), moles to particles, and concentration conversions (M, mM, µM, nM). Essential for stoichiometry, solution preparation, and lab work. Enter values and select units—conversion is instant. Handles common chemistry and physics unit conversions.
When to use
Use for chemistry homework, lab calculations, or stoichiometry. Example: 2 mol water (18 g/mol) = 36 g. 1 M = 1 mol/L. Convert between concentration units (M, mM, µM). Students solve stoichiometry problems. Lab technicians prepare solutions. Convert concentration for dilution calculations. Moles to grams for weighing. Particles to moles for counting. Essential for chemistry and physics. Check your textbook for molar masses. Use correct units for your problem. Saves time on manual calculations.
How to use
Select conversion type. For molarity: enter concentration and choose units (M, mM, µM, nM). For moles ↔ mass: enter moles or grams and molar mass (g/mol). For moles ↔ particles: enter moles or particle count. Avogadro's number (6.022×10²³) is used for particle conversions.
Frequently asked questions
- A mole is 6.022141076×10²³ particles (atoms or molecules). It's the SI unit for amount of substance.
- Multiply moles by molar mass (g/mol). For example, 2 mol of water (18 g/mol) = 36 g.
- Molarity (M) is moles of solute per liter of solution. 1 M = 1 mol/L.
