Answer:
1.2 x 10²⁴atoms
Explanation:
Given parameters:
Molar mass of Mg = 24.3g/mol
Mass of Mg = 48.6g
Number of atoms in 1 mole = 6.02 x 10²³ atoms
Solution
We know that
1 mole contains 6.02 x 10²³ atoms
Now we have to find the number of moles that are in the given mass of the magnesium atom.
Number of moles =
Number of moles = = 2mole
Now 2 moles of Mg will contain 2x 6.02 x 10²³ atoms = 1.2 x 10²⁴atoms
Early in the 20th century scientists realised that all matter is made up of atoms. As a result of an experiment carried out by his assistants, Hans Geiger and Ernest Marsden, Ernest Rutherford suggested a model for the atom. The experiment is known as Rutherford's alpha particle scattering experiment.
Glucose is a molecular substance therefore, there are no ionic species in glucose.
Ionic substances dissolve in water to yield ions. Molecular substances do not produce ions in solution. The conductivity of ionic solutions owes to the presence of ions in solutions. Molecular solutions do not conduct electricity due to the absence of ions.
Glucose is a molecular substance hence they are are no ions present hence glucose does not conduct electricity.

Answer:
The correct option in here is the first one: pentane-1,5-diamine. This is also known as cadaverine. This is a common compund that produces that unpleasant odor from the fish.
