Chemistry
1 answer:
oksano4ka [1.4K]2 years ago
4 0

Answer:

90.35 × 10²³ atoms

Solution:

1 molecules of H20 contains 3 atoms,.

And we know that one mole of any molecule contains 6.023 × 10²³ atoms from Avogadro's number,

hence 5 moles of H20 will contain = 5× 6.023 × 10²³ × 3 atoms = 90.35 × 10²³ atoms!

Jaiden is writing a report about the structure of the atom. In her report, she says that the atom has three main parts and two s
yulyashka [42]

Answer:

The smallest constituent of an element is termed as an atom. According to Jaiden, an atom comprises two subatomic particles and three prime parts, however, this is incorrect as an atom comprises three subatomic particles and two main parts. The three subatomic particles are the protons, electrons, and neutrons. All these parts are smaller in comparison to an atom, thus, they are considered as subatomic particles.  

To be considered as an atom, an atom is needed only electrons and neutrons, like hydrogen exhibit one electron and one proton. On the other hand, the overall charge of the atom is not affected by the presence of neutrons, it is the subatomic particle that only enhances the mass of the atom.

What is relative isotopic mass
lidiya [134]

Answer:

Relative atomic mass or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant. The atomic mass constant is defined as being 1/12 of the mass of a carbon-12 atom.
