Ответ:
To compare the two measurements, the quantity we must use is the Molarity, M₂> M₁
Explanation:
To compare the two measurements, the quantity we must use is the Molarity, which is defined by the ratio of the mass of solute to the volume of the solvent.
M = n / V
In this case for the first concentration it is
M₁ = 5 10-3 / 1
M₁ = 0.005 M
For the second concentration we have
M₂ = 0.010 / 1
M₂ = 0.010 M
Therefore, the molarity of the second concentration is greater than the molarity of the first
M₂> M₁
Ответ:
The equation needs to be balanced. There are fewer oxygen atoms in the equation than hydrogen or carbon. ... There is an equal number of each element on both sides of the equation.
