How many atoms are in 1.75 mol CHCL3
vaieri [72.5K]

1 mol = 6.022 x 10²³ atoms

In order to find how many atoms, dimly multiply the amount of moles you have by 6.022 x 10²³ or Avogadro's number.

So you have 1.75 mol CHC1₃ x (6.022x10²³) = 1.05385 x 10²⁴ atoms of CHCl₃

But now you have to round because of the rules of significant figures so you get 1.05 x 10²⁴ atoms of CHCl₃

When placed inside of a magnetic field, nmr active nuclei act in what way? (1 pt)
ololo11 [35]

When placed inside of a magnetic field, the magnetic field that electrons generate aligns in the opposite direction of the applied magnetic field.

Also, someone who is very popular and attracts people has a charming personality. A powerful speaker that attracts many fans has an engaging way of speaking. A magnetic person is attracted to you as if by a magical magnetism. Both meanings of magnetic have to do with the force of attraction. Only ferromagnetic materials such as iron, cobalt and nickel are attracted to magnetic fields strong enough to be considered truly magnetic.

All magnetic fields contain energy, also called magnetic energy. In physics, it is a constant. Magnetic energy is a form of energy from moving charge carriers (electrons) because magnetic fields are generated by electric currents.
