Any one there who would help me with my pr0blem!Please help me,tnx! What is the mass of carbon dioxide if 100 grams of methane is oxidized to carbon dioxide and water?
First write the balanced reaction. It is
CH4 + 2 O2 = CO2 + 2 H2O
Each mole of methane makes one mole of CO2. You start out with 100/16 = 6.25 moles of CH4, and end up with the same number of moles of CO2, which has a mass of 44 g per mole. That makes
6.25 * 44 = 275 g
To put it another way, each carbon atom ends up in a different molecule with a mass 44/16 times larger than the original molecule mass.
Tnx!Drwls
I'm here to help you with your problem! To determine the mass of carbon dioxide produced when 100 grams of methane is oxidized, you'll need to understand the chemical equation for the combustion reaction.
The chemical equation for the combustion of methane (CH4) can be represented as:
CH4 + 2O2 -> CO2 + 2H2O
From the equation, you can see that one mole of methane (CH4) reacts to produce one mole of carbon dioxide (CO2). This means that the molar mass of methane will be equal to the molar mass of carbon dioxide.
To calculate the molar mass of carbon dioxide (CO2), you need to consider the atomic masses of carbon (C) and oxygen (O). The atomic mass of carbon is approximately 12.01 grams per mole, and each oxygen atom has an atomic mass of about 16.00 grams per mole.
The molar mass of carbon dioxide is then calculated as:
(1 * atomic mass of carbon) + (2 * atomic mass of oxygen)
= (1 * 12.01 g/mol) + (2 * 16.00 g/mol)
= 12.01 g/mol + 32.00 g/mol
= 44.01 g/mol
So, the molar mass of carbon dioxide is approximately 44.01 grams per mole.
Since methane (CH4) has a molar mass of approximately 16.04 grams per mole, you can convert the mass of methane to moles by using the equation:
moles = mass / molar mass
So, if you have 100 grams of methane, you can calculate the number of moles:
moles of methane = 100 g / 16.04 g/mol
≈ 6.23 mol
Since the molar ratio between methane and carbon dioxide is 1:1, the number of moles of carbon dioxide produced will also be 6.23 mol.
Finally, to determine the mass of carbon dioxide produced, use the equation:
mass = moles × molar mass
mass of carbon dioxide = 6.23 mol × 44.01 g/mol
≈ 274.22 grams
Therefore, when 100 grams of methane is oxidized to carbon dioxide and water, the mass of carbon dioxide produced is approximately 274.22 grams.
