what is the mass of 1 mole of carbon dioxide (CO2), and silicon dioxide (SIO2)?
find the molar mass of each.
look at the periodic table!
CO2
12g/mol + 2(16.0g/mol)
44 g/mol
yes, and solve for SiO2 just the way showed you!
To determine the mass of 1 mole of a substance, we need to know the molar mass of that substance. The molar mass is the mass of one mole of a substance and is usually expressed in grams per mole (g/mol).
To calculate the molar mass of a compound like carbon dioxide (CO2) or silicon dioxide (SiO2), we need to consider the atomic masses of the elements involved.
The atomic masses of carbon (C), oxygen (O), and silicon (Si) can be found on the periodic table.
The atomic mass of carbon (C) is approximately 12.01 g/mol, while the atomic mass of oxygen (O) is approximately 16.00 g/mol. Therefore, to calculate the mass of 1 mole of carbon dioxide (CO2), we add the atomic masses of carbon and two oxygen atoms together:
Molar mass of CO2 = (12.01 g/mol) + 2 × (16.00 g/mol) = 44.01 g/mol
The molar mass of carbon dioxide (CO2) is 44.01 g/mol.
Similarly, to calculate the molar mass of silicon dioxide (SiO2), we add the atomic masses of silicon and two oxygen atoms together:
The atomic mass of silicon (Si) is approximately 28.09 g/mol. Therefore, the molar mass of silicon dioxide (SiO2) is:
Molar mass of SiO2 = (28.09 g/mol) + 2 × (16.00 g/mol) = 60.09 g/mol
The molar mass of silicon dioxide (SiO2) is 60.09 g/mol.
