How many grams of O2 will be formed from 18.65 moles of KClO3?

27.98moles

Explanation:

Given parameters:

Number of moles of KClO₃  = 18.65moles

Unknown:

Mass of O₂  = ?

Solution:

The reaction is a decomposition reaction represented with balanced equations as shown below;

            2KClO₃   →   2KCl  + 3O₂

We have to solve from the known to the unknown. The known here is number of moles of KClO₃ .

 From the balanced reaction equation; we have;

                  2 moles of KClO₃ giving 3 moles of O₂

                 18.65 moles of KClO₃ will produce     = 27.98moles

the answers would be

the first one and the second one

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
