The question is incomplete , complete question is :
Report the precise concentration of the undiluted stock solution #1 of TZ in micromoles per liter. This is your most concentrated (undiluted) standard solution for which you measured the absorbance. Use 3 significant figures. Molarity (μmol/L) =31.5
Given: [TZ] = 0.5461 mol/L
Answer:
The concentration of TZ solution in μmol/L is 546 μmol/L
Explanation:
Molarity of the TZ solution = 0.5461 mol/L
This means that 0.5461 moles of TZ are present in 1 L of solution.
Moles of TZ = 0.5461 mol
So, the concentration of TZ solution in μmol/L is :
546.1 μmol/L ≈ 546 μmol/L
Answer:
True
Explanation:
An orbital is is the space occupied by a pair of electrons. The maximum number of electrons in an orbital is 2.
The maximum number of electrons in in the orbitals are two.
For s-sublevel with one orbital we have two electrons
p-sublevel with three orbitals we have six electrons
d - sublevel with five orbitals we have ten electrons
f - sublevel with seven orbitals we have fourteen electrons
Each orbital can take a maximum of two electrons.
When calcium joins with calcium its follows the following equation:
