Answer:

At a partial pressure of 2.470 atm, solubility of O_{2} is 1.03 M

Explanation:

The given problem can be solved by using Henry's law

According to Henry's law at a particular temperature for a particular gas and solvent:                        \frac{S_{1}}{S_{2}}=\frac{P_{1}}{P_{2}}

where, S_{1} and S_{2} are solubility of the gas at a partial pressure of P_{1} and P_{2} respectively.

Here, S_{1}=0.0500M, P_{1}=0.120atm and P_{2}=2.470atm

So, S_{2}=\frac{S_{1}P_{2}}{P_{1}}=\frac{(0.0500M)\times (2.470atm)}{0.120atm}=1.03M

Hence, at a partial pressure of 2.470 atm, solubility of O_{2} is 1.03 M

The density of lead is 11.3g/cm^3 and the density of chromium is 7.14g/cm^3. If we have one gram of each metal, what is the rati
Lady bird [3.3K]

The ratio of the volume of lead to the volume of chromium is 22 : 35

Density is simply defined as the mass of a substance per unit volume of the substance.

<h3>Density = mass / volume </h3>

To solve the question given above, we'll begin by calculating the volume of lead and chromium. This can be obtained as follow:

<h3>For Lead:</h3>

Mass of lead = 1 g

Density of lead = 11.3 g/cm³

<h3>Volume of lead =? </h3>

Density = mass /volume

11.3 = 1 / Volume

Cross multiply

11.3 × Volume = 1

Divide both side by 11.3

Volume = 1 / 11.3

<h3>Volume of lead = 0.088 cm³</h3>

<h3>For Chromium:</h3>

Mass of chromium = 1 g

Density of chromium = 7.14 g/cm³

<h3>Volume of chromium =? </h3>

Density = mass /volume

7.14 = 1 / Volume

Cross multiply

7.14 × Volume = 1

Divide both side by 7.14

Volume = 1 / 7.14

<h3>Volume of chromium = 0.14 cm³</h3>

Finally, we shall determine the ratio of the volume of lead to the volume chromium. This can be obtained as follow:

Volume of lead = 0.088 cm³

Volume of chromium = 0.14 cm³

<h3>Ratio of the volume of lead to chromium =? </h3>

Ratio = Volume of lead / Volume of chromium

Ratio = 0.088 / 0.14

Ratio = 22 / 35

<h3>Ratio = 22 : 35</h3>

Therefore, the ratio of the volume of lead to the volume chromium is 22 : 35
