how to calculate grams in carbon dixoide??
grams = mols x molar mass
grams CO2 = mols CO2 x 44
To calculate the number of grams in carbon dioxide (CO2), you need to know the number of moles of CO2 and the molar mass of CO2.
The molar mass of CO2 is determined by adding up the atomic masses of the carbon and oxygen atoms.
1. Find the molar mass of carbon (C) and oxygen (O) from the periodic table. The atomic mass of carbon is approximately 12.01 grams per mole, and the atomic mass of oxygen is about 16.00 grams per mole.
2. Multiply the molar mass of carbon by the number of carbon atoms in CO2, which is 1.
Molar mass of carbon = 12.01 g/mol x 1 = 12.01 g/mol
3. Multiply the molar mass of oxygen by the number of oxygen atoms in CO2, which is 2.
Molar mass of oxygen = 16.00 g/mol x 2 = 32.00 g/mol
4. Add the molar masses of carbon and oxygen to find the molar mass of CO2.
Molar mass of CO2 = 12.01 g/mol + 32.00 g/mol = 44.01 g/mol (rounded to two decimal places)
Now that you know the molar mass of CO2, you can calculate the number of grams in carbon dioxide using the formula:
grams CO2 = moles CO2 x molar mass of CO2
For example, if you have 2 moles of CO2:
grams CO2 = 2 mol x 44.01 g/mol = 88.02 grams of CO2
Therefore, there are 88.02 grams of carbon dioxide in 2 moles.
