<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

riadik2000 [5.3K]

The other students in the lab should be notified next in this type of scenario.

<h3>What is an acid?</h3>

This is a substance which donates protons and is very corrosive. It also turns blue litmus paper red.

When it was spilled and baking soda was used to neutralize it on the floor , it is best to inform the other students too so as to prevent them from being exposed by mistake thereby reducing risk of injury.

1. Which of the following is NOT a cation?
Bezzdna [24]
Hey Madoudou


The correct answer is option B (sulfate)


The reason is because "Sulfate" has a negative sign.

In order for it to be a cation, it must have positive sign such as "iron(lll)ion
