When heated kclo3 decomposes into kcl and o2 (> 2kcl+3o2 )if this reaction produced 31.9 g of kcl, how much o2 was produced in grams

12 grams of oxygen

Explanation:

To calculate the moles, we use the equation:

For

Given mass = 31.9 g

Molar mass of   = 122.5 g/mol

Putting values in above equation, we get:

2 moles of produces 3 moles of

0.26 moles of produces = moles of

Mass of

Thus 12 grams of oxygen was produced.

the ratio of the conjugate base to the acid required to attain the desired ph.
