How many grams of co2 are used when 7.0 g of o2 are produced?

Answer : The mass of used are 9.68 grams.

Explanation : Given,

Mass of = 7.0 g

Molar mass of = 32 g/mole

Molar mass of = 44 g/mole

The balanced chemical reaction will be,

First we have to calculate the moles of .

Now we have to calculate the moles of .

From the balanced chemical reaction we conclude that,

As, 1 mole of produced form 1 mole of

So, 0.22 mole of produced form 0.22 mole of

Now we have to calculate the mass of .

Therefore, the mass of used are 9.68 grams.

yes
