The answer is H—F. Fluorine is the most electronegative of the four halogens (and, in fact, of all the elements), so it does the best job of gathering the shared electrons to itself. Therefore, the bond with F is the most polar
Answer:
Explanation:To find the number of moles of solute in a volume of a solution, we need to multiply volume by concentration. BUT we also need to check that the units are the same. Molarity (M) is moles per liter, so we need to convert 250mL to L.
250mL=0.250L
Now we can multiply the concentration by volume.
0.4M*0.250L
