Explanation:
The grams of solute are required.
The mass of solute is 3.5 g
c = Molarity = 0.1 M
M = Molar mass = 350 g/mol
V = Volume of solution = 100 mL = 0.1 L
n = Number of moles
m = Mass of solute
Molarity is given by
Molar mass is given by

Answer:
39.998
Explanation:
Hello, have a periodic table handy!
Molar mass is the molecular weight of a compound; sum of all of the mass in grams (from the periodic table) from each and specific atom.
In the periodic table, the molecular weight of an atom is usually shown on the bottom of the element.
In NaOH, there are three atoms in that compound. Na (sodium), O (oxygen), and H (hydrogen).
For Na, the molecular weight is 22.99
For O, the molecular weight is 16.00
For H, the molecular weight is 1.008.
Add all of those values up together to get the molar mass of NaOH being 39.998
The principal quantum number of the first d shell is three. The principal quantum number determines the size of the orbital. The secondary divides the shell into subshells called orbitals and designated by the letters s, p, d, f. From the sequence of the electron configuration, it can be seen that at a principal quantum number of three the d shell first appear.
