Best Answer

The mass of one mole of oxygen atoms is listed on the periodic table (15.999g). Multiply this by three. Be careful. Oxygen is almost never found outside of a molecule. If you are looking for the mass of three moles of oxygen gas, that is three moles of O2. So, you will need to multiply the mass of the atom by two, then multiply by the number of moles.

To find the mass of 3 moles of oxygen atoms, you need to know the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams per mole. So, for 3 moles of oxygen atoms, the mass would be 3 moles x 16 grams/mole = 48 grams.

How many atoms of oxygen are contained in 44g of CO2?

There are 1.5 x 10^23 atoms of oxygen in 44g of CO2. This can be calculated by converting the mass of CO2 to moles, using the molar mass to find the number of moles of oxygen, and then multiplying by Avogadro's number to find the number of atoms.


How many oxygen atoms are there in 7.00 g of sodium dichromate na2cr2o7?

In one mole of sodium dichromate (Na2Cr2O7), there are 7 oxygen atoms. To find the number of moles in 7.00 g, you need to divide 7.00 g by the molar mass of Na2Cr2O7 to find the number of moles of Na2Cr2O7. Then, multiply the number of moles by 7 to find the number of oxygen atoms in 7.00 g of sodium dichromate.


What is the number of moles of oxygen atoms is 35.2 g of oxygen?

There are 2 moles of oxygen atoms in 35.2 g of oxygen. This is calculated by first finding the molar mass of oxygen (16 g/mol), then using the formula: moles = mass / molar mass.


How many moles of atoms of oxygen are in 49 grams of sulfuric acid?

To find the number of moles of atoms of oxygen in sulfuric acid (H2SO4), we need to calculate the molar mass of sulfuric acid. The molar mass of sulfuric acid is 98 g/mol. Oxygen constitutes 64 g/mol in sulfuric acid. Therefore, in 49 grams of sulfuric acid, there are 49/98 = 0.5 moles of sulfuric acid. Since each mole of sulfuric acid contains 4 moles of oxygen atoms, there are 0.5 moles x 4 = 2 moles of oxygen atoms in 49 grams of sulfuric acid.


How many atoms of oxygen are contained in 47.6 g of al2(co3)3?

To find the number of oxygen atoms in 47.6 g of Al2(CO3)3, first calculate the molar mass of Al2(CO3)3, which is 233.99 g/mol. Then, divide the given mass by the molar mass to find the number of moles (0.2032 mol). Finally, use the chemical formula to determine that there are 0.6096 moles of oxygen atoms, which is 3.67 x 10^23 atoms.

What is the number of oxygen atoms in 90 g of potassium permanganate?

The molar mass of potassium permanganate (KMnO4) is 158.034 g/mol. The molar ratio between oxygen atoms and KMnO4 is 4:1. Therefore, in 90 g of KMnO4, there are 90/158.034 moles of KMnO4. Multiply this by 4 to find the number of moles of oxygen atoms, then multiply by Avogadro's number to find the number of oxygen atoms.


What is the mass of 0.2 moles of oxygen atoms?
