Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.

To calculate the total pressure inside the container, we use the law given by Dalton, which is:

$P_T=p_{N_2}+p_{O_2}+p_{Ar}$

We are given:

Vapor pressure of oxygen gas, $p_{O_2}$ = 40.9 kPa

Vapor pressure of nitrogen gas, $p_{N_2}$ = 23.3 kPa

Vapor pressure of argon, $p_{Ar}$ = 13.7 kPa

Putting values in above equation, we get:

$p_T=23.3+40.9+13.7\\\\p_{T}=77.9kPa$

Hence, the total pressure inside the container is 77.9 kPa

Complete Question:

This diagram shows a marble with a mass of 3.8 grams (g) that was placed into 10 milliliters (mL) of water. Using the formula V M D = , what is the density of the marble?

(See attachment for full diagram)

Answer:

1.27 g/cm³

Explanation:

First, find the volume of rock:

Volume of rock = volume of water after rock was placed - volume of water before rock was placed

Volume of rock = 13 - 10 = 3ml

Density of rock = grams of rock per 1 cm³

Note: 1 ml = 1 cm³

Let x represent amount of rock per 1 cm³

Thus,

3.8g = 3 cm³

x = 1 cm³

Cross multiply

1*3.8 = 3*x

3.8 = 3x

3.8/3 = 3x/3

1.27 = x

Density of rock = 1.27 g/cm³
