What part of it are you confused about
Answer:
hmmm
Explanation:
hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm
There are a total of four quantum numbers that govern the
electrons. These are the principal quantum number (n), the angular quantum
number (l), the magnetic quantum number (ml) and lastly the spin quantum number
(ms). Each electron has a unit set of the four quantum numbers.
Since the first 3 quantum numbers is already specified, so
the remaining to be filled is the ms quantum number which can only have values
of +1/2 and -1/2. So we have 2 electrons.
Answer:
<span>2 electrons</span>
10 / (7.89) (2)
molarity equation is M = Moles of solute / Liters of solution
7.89 = Moles of solute / 2
(7.89)(2). The question asks for the molar mass which is defined as g/mol. Dividing would give you the unknown compound.
<span>MM = 10g / (7.89)(2)</span>
