Given the following chemical reaction: 2 o2 + ch4 co2 + 2 h2o what mass of ch4 is required to completely react with 100 grams of o2?

Answer : The mass methane required is, 25 g

Explanation : Given,

Mass of oxygen gas = 100 g

Molar mass of oxygen gas = 32 g/mole

Molar mass of methane gas = 16 g/mole

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, 2 moles of react with 1 mole of

So, 3.125 moles of react with moles of

Now we have to calculate the mass of

Therefore, the mass methane required is, 25 g
