I have been analyzing water samples on a spectrophotometer and the readings are in mg/L and I need to change them into micromoles per liter.
mg/L divided by 1000 is g/L.
g/L divided by the molecular mass in g/mole is mole/L.
mole/L x 1,000,000 is µmole/L.
Approximate concentrations are require in compared with the WHO permissible limts
