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:
Agroup one.B group seven. lonic/electrovalent bonding.
sodium chloride, 2,8. 2,8,8
Explanation:
the reason why it is an lonicbonding is because it is a force of attraction between opposite charges.it involves the transfer of electrons from a metal to a non-metal.
The answer you're looking for is B. The bond will be ionic.
