The formula weight of potassium dichromate (k2cr2o7) is __________ amu.
Gre4nikov [31]

The given compound is K_{2}Cr_{2}O_{7}

Each formula unit of K_{2}Cr_{2}O_{7} has 2 mol Potassium (K) atoms, 2 mol Chromium (Cr) atoms and 7 mol Oxygen (O) atoms.

Atomic weight of potassium is 39.0983 amu

Atomic weight of Chromium is 51.9961 amu

Atomic weight of Oxygen is 15.9994 amu.

Therefore the formula weight of K_{2}Cr_{2}O_{7} =

2 * 39.0983 amu + 2 * 51.9961 amu + 7 * 15.9994 amu

= 294.1846 amu
