We did not draw dots (electrons) around S.but it has six single bonds.for one single bond occupy two electrons.
TOTAL TWELVE (12) ELECTRONS around S

The solubility of carbon dioxide in water is 0.161 g CO2in 100 mL of water at 20ºC and 1.00 atmCO2. A soft drink is carbonated w

Sedbober [7]

<u>Answer:</u> The solubility of carbon dioxide at 5.50 atm is $0.886g/100mL$

<u>Explanation:</u>

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{A}=K_H\times p_{A}$

Or,

$\frac{C_{1}}{C_{2}}=\frac{p_{1}}{p_2}$

where,

$C_1\text{ and }p_1$ are the initial concentration and partial pressure of carbon dioxide

$C_2\text{ and }p_2$ are the final concentration and partial pressure of carbon dioxide

We are given:

$C_1=0.161g/100mL\\p_1=1.00atm\\C_2=?\\p_2=5.50atm$

Putting values in above equation, we get:

$\frac{0.161g/100mL}{C_2}=\frac{1.00atm}{5.50atm}\\\\C_2=\frac{0.161g/100mL\times 5.50atm}{1.00atm}=0.886g/100mL$

Hence, the solubility of carbon dioxide at 5.50 atm is $0.886g/100mL$

Barium acetate, Ba(C2H3O2)2, is a common barium salt that is highly poisonous. It was featured in a 2001 episode of Forensic Fil

aleksley [76]

Answer:

209.68

Explanation:

The only number that is relevant (though the rest are quite interesting) is the last one 1.98 * 10^24

1 mole of Barium Acetate Contains 6.02*10^23 particles.

There are 4 moles of carbon to every mole of Barium Acetate.

1.98 * 10^24 atoms / (4*6.02*10^23)

0.8223 moles of Ba(C2H3O2)2

Ba = 137

4C = 4*12 48

6H = 6*1 6

4O = 4*16 64

1mole 255 grams

0.8223 * 255 = 209.68 grams

I have used rounded masses for these elements depending on the periodic table you use. Go through the question with your masses to get a more accurate answer. My answer will not differ by much. It is a guide.
