A mixture of gases at a total pressure of 95 kPa contains N₂, CO₂, and O₂. The partial pressure of the CO₂ is 24 kPa and the par

Zinaida [17]

Answer:

23 kPa = Partial pressure O₂

Explanation:

In a mixture of gases, the sum of partial pressure of each gas that contains the mixture = Total pressure

Total pressure = Partial pressure N₂ + Partial pressure CO₂ + Partial pressure O₂

95 kPa = 48 kPa + 24 kPa + Partial pressure O₂

95 kPa - 48 kPa - 24 kPa = Partial pressure O₂

23 kPa = Partial pressure O₂

An empty Erlenmeyer flask weighs 241.3 g. When filled with water (d = 1.00 g/cm³), the flask and its contents weigh 489.1 g.

Viefleur [7K]

The answer is- Mass of flask = 608.04 g

Density (d) is defined as mass of substance divided by its volume. Thus, if mass and density are known, then Volume can be determined.

What is the formula of mass in terms of density?

Let mass of substance be 'm' and volume be 'V'. Thus, as per the definition of density, it is expressed as-

$d = \frac{m}{V}$

Thus, mass can be expressed as-

$m = d * V$

Now, mass of empty flask = 241.3 g and the mass of (flask + Water) = 489.1 g.

Thus, mass of water = $489.1\ g- 241.3\ g = 247.8\ g$ .

Thus, mass of water = 247.8 g and density of water = $1.00\ g/cm^3$ . Its volume is calculated as-

$V = \frac{247.8\ g}{1.00\ g/cm^3}=247.8\ cm^3$

Volume of flask = 247.8 $cm^3$ .
Then when this flask is filled with chloroform (d = $1.48 g/cm^3$ ), the mass of chloroform is-

$m = d * V = (1.48\ g/cm^3) * (247.8\ cm^3)= 366.74\ g$

Hence, the mass of flask becomes = $241.3\ g + 366.74\ g = 608.04\ g$
