The molarity of a solution is the number of moles of a substance in one liter of that substance.
The molar mass of ammonium sulfate (NH4)2SO4 is 132.14 grams/mole
Calculate the moles of ammonium sulfate:
(4.50 grams)/(132.14 grams/mole) = 0.0341 moles of ammonium sulfate
convert mL to Liters 250. mL becomes 0.250 liters
Take the number of moles over the number of liters
0.0341 moles / 0.250 liters = 0.136 molar or 0.136M = molarity of the solution
C. 6, 1, 0, -1/2
Explanation:
The four quantum numbers are:
- Principal quantum number (n): this represents the energy level in which an orbital is located.
- Azimuthal quantum number gives the shape of the orbitals in subshells accommodating the electrons.
- Magnetic quantum number gives the number of spatial orientations or degeneracy of the orbitals in the subshells.
- Spin quantum number describes the spinning of an electron in either clockwise or anticlockwise directions.
To know the electron with the highest energy, we use the principal quantum number values.
n values takes whole numbers i.e n = 1,2,3,4,5,6,7.............
The higher the value, the higher the energy level.
From the given quantum numbers, C has the highest energy levels.
