The atomic mass unit is presently based on assigning an exact integral mass (in amu) to an isotope of carbon.
<h3>What is the atomic mass?</h3>
The atomic mass is a measurement used in physics and chemistry to denote the average atomic mass of a given element which is measured in the atomic mass unit or amu.
In conclusion, the atomic mass unit is presently based on assigning an exact integral mass (in amu) to an isotope of carbon.

Answer:
molarity 0.1
Explanation:
mass of copper nitrate =2.4
no of moles exist in 120ml= 2.4/187.5=0.0128mole
molarity =.0.0128/.12=0.1m
False; Because when 2 substances are mixed another substance is created.
The element that has been reduced in the chemical equation is
.
The given reaction has been:

The reaction has been the redox reaction, in which the one of the reactant has been oxidized, and the other has been reduced in the chemical reaction.
<h3>Reduction in the reaction</h3>
The reduction has been defined as the gain of electrons. In the given reaction, the Mg loses 2 electrons and has been converted to the Mg ion.
Thus, Mg has been oxidized in the reaction.
The Cl has been present as the diatomic molecule and with the gain of two electrons from the Mg it has been converted to two chloride ions.
Thus, the element that has been reduced in the chemical equation is
.

Answer:
As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+
Explanation:
The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.
However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a
species which is simply a diatomic ion but not a compound.
