Question

the volume is 207.16ml for the "Dry" oxygen at STP..

I need to determine the purity of the orginal potassium chlorate sample. Do I need moles of oxygen?

(Moles)/(0.765g)X100%  ??

A 0.765g sample of umpure KCI03, was decomposed by thermal decomposition into oxygen gas the potassium
chloride the oxygen, 222.50ml, was collected in a eudiometer over water at the temperature 20.00C and a
pressure of 777.00mmHg. the water level in the eudimeter is 42.2mm above the water level in the beaker. the
vapor pressure of water at this temperature is 17.54 mmHg. 1mmHg= 13.6mmH20. what is the volume of the
dry oxygen at STP?
