4% mass / volume :
4 g ---------> 100 mL
1.2 g ------- ? mL
V = 1.2 * 100 / 4
V = 120 / 4
V = 30 mL
hope this helps!
The molar mass of the product is equal to 62g/mol.
<h3>Mole calculation</h3>
To calculate the molar mass of a compound it is necessary to have knowledge of the atomic mass of all the elements involved.
In the case of the question, we have the reaction between flourine and magnesium, which represents the element of group 2 with the presented electronic configuration.
Thus, we have the following reaction:
So, just add the molar masses, having:
So, the molar mass of the product, round to the nearest tenth, is equal to 62g/mol.

6.5 is slightly acidic - so the answer is B.
This is due to 7 being neutral
7-14 is basic
0-7 is acidic
In ionic bonds, one atom gives one or more electrons to another atom so both can get closer to 8 valence electrons. Example: In potassium chloride (KCl), Potassium gives up one valence electron to chlorine, so that the outer shell of potassium has 8 valence electrons. This happens only between metals and nonmetals.
In covalent bonds, atoms share their electrons to reach 8 valence electrons. Example: In water (H2O), Oxygen shares one valence electron with one atom of hydrogen, and another valence electron with another atom of hydrogen. Oxygen now has 8 (4 unshared + 2 of its own + 1 from hydrogen + 1 from hydrogen), and each hydrogen has 2 valence electrons: one of its own and one from oxygen [ note that hydrogen only needs 2 valence electrons to be complete instead of 8].
In metallic bonds between metals, the valence electrons move much more freely than in other bonds. This free characteristic makes metals how they are: ductile, malleable, sectile, conductive, etc.
