chemCal is a basic chemistry concentration (molarity, moles per liter) and dilutions calculator for students of chemistry, biology, biochemistry, and biomedical sciences at school, college or university.
The calculator is easy to use, just input the concentrations (Molar, mM etc.), molecular weights, percentages, and dilutions (liters) you wish to use, and you get the answer. The calculator can also easily and quickly convert between different unit values such as milli (m), micro (μ), nano (n), pico (p) and femto (f).
* easy input
* rapid conversion between units (e.g. milli, micro, pico, femto)
* calculate concentration (molarity) of a solution for a given mass of compound and volume of water
* calculate the mass of a chemical needed to make a solution of a certain volume and concentration
* easily work out lab dilutions

Molar Mass Calc Missing
For the price, even at $3, this app needs a molar mass ("molecular weight") calculator built in. iChemCalc does this but has its own problems (unreadable periodic table, non-alphabetical elements). The Help section is nice because it shows how to set up the calculation if you were to do it using a calculator, like a teacher might request.
Waste of $5
I'm feeling soo ripped off.
With Family Sharing set up, up to six family members can use this app.
