Imagine that 27.0 g of C2H2(g) dissolves in 1.00 L of liquid acetone at 1.00 atm pressure. If the partial pressure of C2H2(g) is

increased to 12.0 atm, what is its solubility in acetone?

<u>Answer:</u> The solubility of C_2H_2(g) at 12.0 atm is 324g/1.00L

Explanation:

We are given:

Mass of C_2H_2(g) = 27.0 grams

Volume of liquid acetone = 1.00 L

Solubility of C_2H_2(g) in liquid acetone at 1.00 atm = 27.0 g / 1.00  L

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 C_2H_2(g)

C_2\text{ and }p_2 are the final concentration and partial pressure of C_2H_2(g)

We are given:

C_1=27.0g/1.00L\\p_1=1.00atm\\C_2=?\\p_2=12.0atm

Putting values in above equation, we get:

\frac{27.0g/1.00L}{C_2}=\frac{1.00atm}{12.0atm}\\\\C_2=\frac{27.0g/1.00L\times 12.0atm}{1.00atm}=324g/1.00L

Hence, the solubility of C_2H_2(g) at 12.0 atm is 324g/1.00L

Answer:

ok :)

Explanation: genetically modified organisms (GMOs) are being made by inserting a gene from an external source such as viruses, bacteria, animals or plants (etc) into foods. Genetically modified foods seem to be not as healthy as unmodified foods, according to research. also many people are against it due to the fact that some people go overboard and add too many genetically modified organisms, which causes health risks and unfortunately harms people. sometimes genetically modified food contains toxins and antibiotics. srry i couldnt find much on the process but this is based off my background knowledge so yeah
