How many atoms are present in 16g of O and 8g of S?
To calculate the number of atoms present in a given mass of a substance, we need to use the concept of molar mass and Avogadro's number. The molar mass of oxygen (O) is approximately 16 g/mol, and the molar mass of sulfur (S) is approximately 32 g/mol. For oxygen: 16g / 16 g/mol = 1 mol of O. 1 mol of O contains 6.022 x 10^23 atoms (Avogadro's number). Therefore, 16g of O contains 6.022 x 10^23 atoms. For sulfur: 8g / 32 g/mol = 0.25 mol of S. 0.25 mol of S contains 0.25 x 6.022 x 10^23 atoms = 1.5055 x 10^23 atoms. Therefore, there are approximately 6.022 x 10^23 atoms in 16g of oxygen and approximately 1.5055 x 10^23 atoms in 8g of sulfur.
What is 12g of carbon with 32g of oxygen?
To calculate the moles of each element, you need to divide each mass by the molar mass. The molar mass of carbon is 12g/mol and oxygen is 16g/mol. 12g of carbon divided by 12g/mol gives 1 mole of carbon. 32g of oxygen divided by 16g/mol gives 2 moles of oxygen.
How many atoms of oxygen are there in 220g of carbon dioxide?
Atomic mass of C = 14g/mol Atomis mass of O = 16g/mol Molecular mass of CO2 = 12 + 2(16) = 44g/mol number of moles = mass / molecular mass number of moles = 220g / 44g/mol = 5.0mol 1 mole of substance contains approximately 6.02 x 10^23 of its particles 5.0 moles of CO2 have 5.0 x 6.02 x 10^23 = 3.01 x 10^24 CO2 molecules. Each CO2 molecule contains 2 oxygen atoms. Total number of Oxygen atom = 2 x 3.01 x 10^24 = 6.02 x 10^24 atoms
What is the ratio of oxygen atoms to hydrogen atoms in a water molecule?
2 hydrogen, 1 oxygen. The equation for water is H2O, meaning 2 parts hydrogen and 1 oxygen. Oxygen is a bigger element than hydrogen, hydrogen being the least dense substance on earth (which is why it rises in air) External links to a picture of a magnified water molecule:
How can you tell there is more oxygen in hydrogen peroxide than in water?
You can tell that there is more oxygen in hydrogen peroxide than in water because hydrogen peroxide has an extra oxygen atom compared to water. The chemical formula for hydrogen peroxide is H2O2, while the formula for water is H2O. This extra oxygen in hydrogen peroxide makes it a more oxidizing chemical compared to water.

The Avogadro number: 6,02214129(27)×1023.
How many number of moles of carbon dioxide that are contain 16g of oxygen?
To calculate the moles of carbon dioxide, we first need to determine the number of moles of oxygen in 16g. Using oxygen's molar mass of 16 g/mol, we find that there is 1 mole of oxygen in 16g. Since one mole of oxygen reacts with one mole of carbon dioxide in the balanced equation, there will also be 1 mole of carbon dioxide formed.
