How many atoms are present in 16g of O and 8g of S?
16 g O x 1 mol/16 g = 1 mole and 1 mole = 6.02x10^23 atoms of O8g S x 1 mol/32 g = 0..25 moles S and then 0..25 moles x 6.02x10^23 atoms/mole = 1.5x10^23 atoms of S, or rounding to 1 significant figure, you have 2x10^23 atoms of S
How can you tell there is more oxygen in hydrogen peroxide than in water?
In 1 mole of water, the total amount of oxygen is only 16g. But the amount of the same in 1mole of Hydrogen peroxide is 32g. So more oxygen is present in hydrogen peroxide than in water.
What mass of H2O can be made from 24gO oxygen and 16g H2?
24/16 = 1.5 and 18 x 1.5 = 27g
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 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
How many atoms are present in 16g of O?
The Avogadro number: 6,02214129(27)×1023.
How many atoms in 16g of O and 8g of S?
7,5276766125.1023 atoms.
If 16g of oxygen contains 1 mole of oxygen atoms calculate the mass of one atom of oxygen in grams?
1
What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
How many atoms are in 16 grams of oxygen?
1mol O = 16.0g (rounded to 1 decimal place) 1mol O atoms = 6.022 x 1023 atoms 16g O x 1mol/16g = 1mol O 1mol O x 6.022 x 1023atoms/mol = 6.022 x 1023 atoms O
How many atoms in 16g of O?
The Avogadro number: 6,02214129(27)×1023.
How many number of moles of carbon dioxide that are contain 16g of oxygen?
As one mole of CO2 contain 2 oxygen having molar mass 32. Soo there will be 0.50 moles of CO2 which contain 16g of oxygen....!
How many oxygen atoms are present in 40.0 grams of oxygen gas?
Ar of O = 16g/mol Mr of O2 = 2(16) = 32g/mol Using the formula : Number of moles = mass / Mr Number of moles = 40g / 32g/mol = 1.25mols One mole of substance contains the same number of particles as the Avogadro constant, which is 6.02 x 10^23 Number of Oxygen molecules = 1.25 x 6.02 x 10^23 = 7.525 x 10^23 Each Oxygen molecules contain two Oxygen atoms Number of Oxygen atoms = 7.525 x 10^23 = 1.505 x 10^24 atoms
What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
How many moles of atoms are there in 3.968x1023 atoms Mg?
Divide that number by Avogadro's number: 3.968x10(23) / 6.02x10(23) = 0.659mol Mg, which would be about 16g.
How many atoms are present in 16g of O and 8g of S?
16 g O x 1 mol/16 g = 1 mole and 1 mole = 6.02x10^23 atoms of O8g S x 1 mol/32 g = 0..25 moles S and then 0..25 moles x 6.02x10^23 atoms/mole = 1.5x10^23 atoms of S, or rounding to 1 significant figure, you have 2x10^23 atoms of S
How can you tell there is more oxygen in hydrogen peroxide than in water?
In 1 mole of water, the total amount of oxygen is only 16g. But the amount of the same in 1mole of Hydrogen peroxide is 32g. So more oxygen is present in hydrogen peroxide than in water.
