Calculate the volume of oxygen at 27C and 740 mmHg which could be obtained by hesting 10g of potassium trioxochlorate (v)
2KClO3 ==> 2KCl + 3O2
mols KClO3 = grams/molar mass KClO3
Using the coefficients in the balanced equation, convert mols KClO3 to mols O2.
Convert mols O2 to volume using PV = nRT.
