How much does 1.9 mol of carbon dioxide
weigh?
Answer in units of g
C = 12.01
O2 = 16*2 = 32
Total = 44.01 g
take the molar mass which in this case is 44.01g and then multiply it by the number of mols you have which in this case is 1.9.
To determine the weight of carbon dioxide (CO2) with a given amount of moles, you need to know the molar mass of carbon dioxide.
The molar mass of carbon dioxide is calculated by adding the atomic masses of its constituent elements, which are carbon (C) and oxygen (O).
The atomic mass of carbon (C) is approximately 12.01 g/mol, and the atomic mass of oxygen (O) is approximately 16.00 g/mol.
So, to calculate the molar mass of carbon dioxide (CO2), you would multiply the atomic mass of carbon (12.01 g/mol) by the number of carbon atoms in carbon dioxide (1), then add the product to the atomic mass of oxygen (16.00 g/mol) multiplied by the number of oxygen atoms in carbon dioxide (2).
Molar mass of carbon dioxide (CO2) = (12.01 g/mol * 1) + (16.00 g/mol * 2) = 44.01 g/mol
Now that we have the molar mass, we can find the weight of 1.9 mol of carbon dioxide.
Weight of 1.9 mol of carbon dioxide = 1.9 mol * 44.01 g/mol = 83.59 g
Therefore, 1.9 mol of carbon dioxide weighs approximately 83.59 grams.
