in the periodic table we have the density of each element ( density(Si) = 2.33), density(O)=1.429). i wonder how we could calculate the density of SiO2 ?
physicist888 said:the density of SiO2 = ?
To calculate the density of SiO2, you need to know the mass and volume of the substance. The formula for density is mass divided by volume. So, to calculate the density of SiO2, divide the mass of SiO2 by its volume.
The mass of SiO2 can vary depending on the amount of substance being measured. However, the molar mass of SiO2 is approximately 60.08 g/mol.
The volume of SiO2 also varies depending on the amount being measured. However, the molar volume of SiO2 is approximately 22.7 cm³/mol.
The mass of SiO2 can be found by looking at the atomic mass of silicon (Si) and oxygen (O) in the Periodic Table. The atomic mass of Si is 28.09 g/mol and the atomic mass of O is 16.00 g/mol. So, the mass of SiO2 (Si+2O) would be 60.08 g/mol.
The density of SiO2 is relatively high compared to other elements in the Periodic Table. It is denser than elements such as iron and copper, but less dense than elements such as lead and gold.
