Answer:
4.15 M
Explanation:
In order to find the molarity of a stock solution of Z, we use the formula;
Co = 10pd/M
where;
p = percentage by mass of Z
d = density of Z
M= molar mass of Z
Substituting values;
Co= 10 * 35 * 1.4/118
C0= 4.15 M
The question is asking to calculate the lewis structure for the anion -CH2CN and abse on my research, Lewis structure is a simple way to keep track of bonding electrons, non-bonding electrons, and formal charges in molecules. I hope you are satisfied with my answer and feel free to ask for more
