Question

How many moles of Hg will be produced from 39.0 of HgO?

Answer 1

Answer;

0.180 moles of HgO

Explanation;

The atomic weight of mercury is 200.5  

The atomic weight of oxygen is 16.0  

Therefore; the molecular weight (per mole) of mercury oxide is 216.5 g

Hence;

Number of moles  = 39 g/(216.5 g/mole)

                              = 0.180 moles of HgO.
