$PO_4^{3 – }$ ion has one atom of phosphorus and four atoms of oxygen, so the number of atoms in this molecule is 1+ 4 =
5
.
How many atoms are present in H2S molecule and PO 43 minus ions?
How many atoms are present in a (i) H2S molecule and (ii) PO43- ion? Answer: (i)
3 atoms
because H2S molecule has two atoms of hydrogen and one atom of sulphur. (ii) 5 atoms because PO43- ion has one atom of phosphorus and four atoms of oxygen.

How many atoms are present in H2?
Hydrogen gas is a diatomic molecule, i.e. There are
1.204 x 10^24 atoms
of hydrogen present in 18 grams of water. Avogadro’s number (6.022 x 10^23) is a collective number which tells you how many molecules of a substance there are in 1 mole of that substance. 1. The hydrogen found in … H2O.
How many atoms are present in human body?
Suzanne Bell, an analytical chemist at West Virginia University, estimates that a 150-pound human body contains about 6.5 octillion
(that’s 6,500,000,000,000,000,000,000,000,000) atoms
. The vast majority of them are hydrogen (humans are almost entirely water, which comprises two hydrogen atoms and an oxygen).
How many atoms are present in a molecule?
In molecular sciences, a molecule consists of a stable system (bound state) composed of
two or more atoms

How do you calculate hydrogen atoms?
Explanation: To determine the number of hydrogen atoms,
divide the mass of ethanol by its molar mass to get moles of ethanol
. Multiply this by six atoms of hydrogen per molecule of ethanol and by Avogadro’s number to get the number of hydrogen atoms.
Is atom present in human body?
About 99 percent of your body is made up of atoms of
hydrogen, carbon, nitrogen and oxygen
. You also contain much smaller amounts of the other elements that are essential for life. … The protons and neutrons inside of an atom’s nucleus are each made up of three quarks.
Who created the human body?
