How many atoms are there in 32g of Sulphur?
32 grams of sulfur will contain 6.022 X 1023 sulfur atoms.
How many atoms are there in 28g of nitrogen gas?
By Avagadro’s law, 1 Nitrogen mole or 28 g of Nitrogen contains 6.023 x 10^23 no. of molecules. Nitrogen, being a diatomic element, the no. of atoms = 2 x 6.023 x 10^23 atoms.
How many amu are in a mole of oxygen?
One mole of anything is the same number of grams as it is atomic mass units (i.e., a mole is a mass conversion factor). Therefore, this 16-gram mole sample of oxygen would have 16 amu. How this 19-year-old earns an extra $3600 per week.
How many atoms of oxygen are there in 32 grams of oxygen?
Each O2 molecule contains two oxygen atoms. Oxygen gas is diatomic so the gas will be in the form of molecules and not the atoms. One molecule of oxygen gas has 2 atoms and 32 grams of oxygen gas is equal to 1 mole of oxygen gas. So one mole of oxygen gas will have two moles of atoms of oxygen.
How much does 32 amu of O2 weigh at STP?
One mole of oxygen gas weighs 32 g at STP. That means 32 amu of O2 will be equivalent to 1 mole. 1 mole of anything contains 6.023×10^23 particles.
What is the number of atoms in 1616g of oxygen?
16 g is equal to 0.5 mole of oxygen molecule. we know in one molecule of oxygen there are 2 atom. Hence in 0.5 mole of oxygen molecule, there are 0.5 * 2 mole of atom of oxygen. that is 1 mole of oxygen atom. Number of particle in one mole = 6.022 * 10^233.
