Maybe Sugar I did that question before I think.
False. They usually give away their electrons to form ionic bonds
On the cumulative Report, it would be much easier to read for the patients if the ranges in parentheses were tabbed over from the actual result instead of printing directly one space after the result.

Explanation:
Sodium fluoride - 5-chloro-2-(2,4-dichlorophenoxy)phenol (1:1:1) | C12H7Cl3FNaO2 |
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
