There should be 4.5 moles
Answer:
The SI base units of length, mass, and time are the meter (m), kilogram (kg), and second (s), respectively. SI units are a metric system of units, meaning values can be calculated by factors of 10. Metric prefixes may be used with metric units to scale the base units to sizes appropriate for almost any application

Answer:
The correct answer to the following question will be Option B (temperature of the water).
Explanation:
- The solubility of that same salt which appears whenever the substance is added in some kind of a fluid which already incorporates another origin of many of its atoms.
- The solubility of such a substance throughout a given quantity of water is predominantly dependent on the whole of the water temperature.
The building of all the profiles is correct; The total number of electrons is correct, as well as the filling of the shells to their entirety. However, some charge calculations are off. First, we see that sodium loses an electron in its structure. Hence, it acquires a charge of +1, not -1. Also, Fluorine gains 2 electrons in its 2p subshell. Thus, its charge is -2, not -1 and this is wrong too. The only correct answer is C; aluminum lose 3 electrons from its p-shell and hence it has a charge of +3.
