What mass of oxygen would form from 2.30 moles of water?

Answer : The mass of oxygen will be, 36.8 grams

Solution : Given,

Moles of water = 2.30 moles

Molar mass of = 32 g/mole

First we have to calculate the moles of oxygen.

The balanced chemical reaction will be,

From the balanced reaction we conclude that

2 moles of water decomposes to give 1 mole of

2.30 moles of water decomposes to give moles of

Now we have to calculate the mass of oxygen.

Therefore, the mass of oxygen will be, 36.8 grams
