This question is a dilution problem. In order to prepare a certain concentration and volume from a stock solution, you have to use the equation,
M1V1 = M2V2
From the equation, you need to calculate the volume you need from the stock solution to be able to have the diluted concentration then dilute it to a certain volume.
(1.0 M) (V1) = (0.1 M) (100 mL)
V1 = 0.1 mL is needed from the 1.0 M HCl solution
Mass to volume
M^3 --> cm^3
Cm^3 --> mL
Centi = 10*-2
7.379*10-4 / 1*10-2 = .07379
I think it might be 8 but not 100 percent took class 2 years ago
There is 118 elements<span> in the periodic table</span>
You that Mg is the metal if in the periodic table it lands between group 1-12. So yeas Mg is a metal because it lands in group 2.
