15.8\% carbon and 84.2\% sulfur. 40.0\% carbon, 6.7\% hydrogen, and 53.3\% oxygen.

How many oxygen atoms are in 3h2so4?

Sulfuric acid contains 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.

How many atoms of O2 are present in 300g of CaCO3?

Explanation: Moles of calcium carbonate, 300⋅g100.09⋅g⋅mol−1 ≅ 3⋅mol . Given the elemental makeup, in such a quantity there are 3 moles of calcium, 3 moles of carbon, and 9 moles of oxygen.

How many oxygen atoms are in G?

1.4. For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 1023 oxygen atoms. Similarly, for one gram atomic weight of silicon with atomic weight of 28 grams, one mole of silicon still contains 6.022 × 1023 silicon atoms.

How many oxygen atoms are in 1g of oxygen?

For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 1023 oxygen atoms.

How many atoms of oxygen are present in 200 gram of CaCO3?

firstly we find the mole of CaCO3 . Now, in CaCO3 1 mol CaCO3 contains 3 mol O . Hence, 36.138*10^23 atoms of oxygen are present in 200 g of caco3.

How many atoms are there in 3h2so4?

Now as there are 3 molecules of sulphuric acid so 7×3 = 21 atoms in total.

How many atoms are present in 200g of CaCO3?

How many number of carbon atoms are present in 250 grams CaCO3?

=250⋅g100.09⋅g⋅mol−1formula mass of calcium carbonate=2.50⋅mol …and thus there are 2.50⋅mol of calcium atoms present, 2.50⋅mol of carbon atoms present, and 7.50⋅mol of oxygen atoms present; are you clear as to how we got these numbers?

How many oxygen atoms are in a 225g sample of O2?

Answer and Explanation: There are 84.684375 X 1023 oxygen atoms in a 225-gram sample of O2. Hereof, what will be the number of oxygen atoms in 1 mole of o2?

How many oxygen atoms are there in 225 grams of KMnO4?

The chemical formula of potassium permanganate (KMnO4) indicates that one mole of the compound contains four moles of O atoms. Use dimensional analysis to calculate the number of O atoms in 1.4238 mol KMnO4. There are ~3.43×10^24 oxygen atoms in 225. grams of potassium permanganate.

How many atoms of oxygen are in 256G of oxygen?

Therefore 256 g of oxygen (O2) has 9.63x 10^24 atoms of oxygens. Why does oxygen have 2 atoms? Oxygen atom has atomic number as 8 so it has its K shell completely filled with 2 electrons. So oxygen atom shares 2 electrons with another oxygen atom to form a diatomic molecule.

How many molecules of oxygen are in 7031 moles of oxygen?

So, 7.031 mol contains 7.031 x 6.022 x 10^23 = 4.234 x 10^24 molecules. Since oxygen is diatomic, the number of oxygen atoms is 8.468 x 10^24. The molar mass of Oxygen is 15.995 grams per mole.
