How do you find the number of atoms in 1 gram of an element?

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro’s number: 6.02 x 10^23.

What are phosphorus atoms?

Phosphorus is a chemical element with the symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.

What type of atoms are in phosphorus?

This is PH3, also known as phosphine. Phosphine is a gas and is made up of three hydrogen (H) atoms and one phosphorus (P) atom. The hydrogen atoms share each of their electrons to fill the outer shell of the phosphorus atom.

How many 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 each element are in NH4 3po4?

In ammonium phosphate, the NH4 is enclosed in parenthesis. The sum of the atoms within the parenthesis is five. The number three after the closed parenthesis indicates a total of three ammonium groups within the compound. Since each group has five atoms multiplying three groups by five atoms produces 15 atoms.

What is the chemical formula for phosphoric acid?

Phosphoric Acid is a weak acid with chemical formula H 3 PO 4. Phosphoric Acid is an acid-containing four atoms of oxygen, one atom of phosphorus, and three atoms of hydrogen.

What happens when red phosphorus is heated with HNO3?

Red phosphorus when heated with conc.HNO3 yields orthophosphoric acid. On a large scale, it is prepared by treating phosphorite rock with dil.H2SO4. Phosphoric acid may be obtained by adding sulphuric acid to the phosphate of baryta suspended in water.
