Answer:
The molar concentration of the final solution is 1.71
Explanation:
Molarity is a way of expressing the concentration of solutions and indicates the number of moles of solute dissolved per liter of solution.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution.:
Molarity is expressed in units ().
Then, the number of moles of solute can be calculated as:
number of moles of solute= molarity* volume
So, in this case, the final concentration can be calculated as:
where, being 65 mL=0.065 L, 125 mL=0.125 L and 190 mL=0.190 L (because 1000 mL= 1 L):
- Total number of moles of solute= 0.065 L*0.513 + 0.125 L*2.33 = 0.033345 moles + 0.29125 moles= 0.324595 moles
- Total volume= 65 mL + 125 mL= 190 mL= 0.190 L
Replacing:
Final molarity ≅ 1.71
<u><em>The molar concentration of the final solution is 1.71 </em></u><u><em></em></u>
Greater the Ka value greater is the acid strength. Among these three acids HClO3 is the strongest acid, with greatest Ka and lowest pKa value (-1), Then comes HBrO3, its the second most strongest acid among the three, its Pka value is 0.7, higher than HClO3 but smaller than HIO3 (i.e. 0.77) which the weakest acid among the three.
If my memory serves me well, each period in the periodic table corresponds to a principal energy level. I think it's correct because periods are the horizontal rows and when you go down you always add <span> one to the principal energy level. Hope it is clear. Good luck!</span>
