How many grams of oxygen are formed when 8.20 moles of koh are formed? 4 ko(s) + 2 h2o(l) → 4 koh(s) + o2(g)

Answer : The mass of oxygen formed are 65.6 grams.

Explanation :

First we have to calculate the moles of

The given balance chemical reaction is:

From the balanced chemical reaction we conclude that,

As, when 4 moles of KOH formed then 1 mole of will be formed

So, when 8.20 moles of KOH formed then mole of will be formed

Now we have to calculate the mass of

Molar mass of = 32 g/mole

Therefore, the mass of oxygen formed are 65.6 grams.
