Answer:

Lewis structure is shown in the image below.

Explanation:

Acetate ion (CH₃COO⁻)

Valence electrons of carbon = 4

Valence electrons of oxygen = 6

Valence electrons of hydrogen = 1

Charge = 1 (Negative which means that the electrons are being added)

The total number of the valence electrons  = 2(4) + 2(6) + 3(1) + 1 = 24

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,  

The Lewis structure is shown in the image below.

If 65.5 ml of HCl stock solution is used to make 450 ml of a 0.675 M HCl dilution, what is the molarity of the stock solution ?
Talja [164]

<u>Answer:</u> The molarity of the stock solution is 4.64 M

<u>Explanation:</u>

To calculate the molarity of the diluted solution, we use the equation:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the stock solution

M_2\text{ and }V_2 are the molarity and volume of diluted solution

We are given:

M_1=?M\\V_1=65.5mL\\M_2=0.675M\\V_2=450mL

Putting values in above equation, we get:  

M_1\times 65.5=0.675\times 450\\\\M_1=4.64M

Hence, the molarity of the stock solution is 4.64 M
