How many grams of co2 are used when 6.5 g of o2 are produced

Answer : The mass of used are 8.8 grams.

Solution : Given,

Mass of = 6.5 g

Molar mass of = 32 g/mole

Molar mass of = 44 g

First we have to calculate the moles of .

Now we have to calculate the moles of

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 mole of produced from 1 mole of

So, 0.20 mole of produced from 0.20 mole of

Now we have to calculate the mass of

Therefore, the mass of used are 8.8 grams.
