How to use Periodic Table & Molar Mass Calculator
- Tap any element (or find it in the list) to see its atomic number, mass, group, period, block and electronegativity; colour the table by category, electronegativity or mass to see the trends.
- Switch to Molar mass and type a formula such as H2SO4, Ca(OH)2 or CuSO4·5H2O.
- Read the molar mass and each element's share, convert grams to moles and particles, and copy the working.
What are the limits of Periodic Table & Molar Mass Calculator?
Atomic masses are the IUPAC standard atomic weights rounded for school and college use; for elements with no stable isotope the mass number of the longest-lived isotope is shown in brackets. Formulas must use correct capitals (Co is cobalt, CO is carbon monoxide).
