Answer:
0.1 M
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 100 mL
Initial concentration (C1) = 0.5 M
Final volume (V2) = 500 mL
Final concentration (C2) =?
Using the dilution formula C1V1 = C2V2, the new concentration of the solution can be obtained as follow:
C1V1 = C2V2
0.5 × 100 = C2 × 500
50 = C2 × 500
Divide both side by 500
C2 = 50/500
C2 = 0.1 M
Therefore, the new concentration of the solution is 0.1 M
D, forms from decomposed material
Answer:
the percent of actual fruit juice in the mixture will be 76%
Explanation:
given that we are mixing 2 bottles the total volume the mixture will be
mixture volume = volume bottle 1 + volume bottle 2 = 48 ounces + 32 ounces = 80 ounces
also the total quantity of juice will be
juice mass in mixture = juice bottle 1 + juice bottle 2 = 48 ounces * 1 + 32 ounces * 0.4 = 60.8 ounces of juice
therefore the concentration of juice in the mixture will be
concentration = 60.8 ounces of juice / 80 ounces = 0.76 (76%)
therefore the percent of actual fruit juice in the mixture will be 76%
The difference in electronegativity between two atoms determines how a polar a bond will be. In a diatomic molecule with two identical atoms, there’s not difference in electronegativity, so the bond is nonpolar or pure covalent.
