If we're talking about the amount of electron rings and the dots within the rings around an atom, the amount will be 1 ring, 2 dots.
It is make the molecule polar.
Answer:
the concentration of new solution = 0.025 M
Explanation:
Given that :
The initial volume V_1 = 15 mL
Initial concentration M_1 = 0.16 M
Final volume V_2 = 95 mL
Final concentration M_2 = ???
We know that M_1 × V_1 = M_2V_2
Making M_2 the subject of the formulae; we have :
M_2 = (M_1 × V_1)/V_2
M_2 = (0.16 × 15)/ 95
M_2 = 0.025 M
Thus, the concentration of new solution = 0.025 M
