Answer:

The answer to your question is 0.186 moles  of CO₂

Step-by-step explanation:

Data

Volume = 2.7 L

Temperature = 24°C

Pressure = 57.2 kPa

moles of CO₂ = ?

Process

1.- Calculate the moles of Propane, use the ideal gas formula

          PV = nRT

          n = PV / RT

- Convert temperature to °K          

  °K = 273 + 24 = 297

- Convert pressure to atm

          1 atm ----------------- 101325 Pa

          x       ------------------  57200 Pa

          x = (57200 x 1)/101325

          x = 0.56 atm

- Substitution

         n = (0.56)(2.7) / (0.082)(297)

- Simplification  

          n = 1.512 / 24.354

- Result

          n = 0.062 moles

2.- Balanced the chemical reaction

                  C₃H₈  +  5O₂   ⇒    3CO₂  +  4H₂O

3.- Calculate the moles of Carbon dioxide

                 1 moles of C₃H₈  ------------------ 3 moles of CO₂

                 0.062 moles      -------------------   x

                 x = (0.062 x 3) / 1

                x = 0.186 moles

Find the range and interquartile range for the data represented by the box plot.
Anarel [89]

<u>Given</u>:

Given that the data are represented by the box plot.

We need to determine the range and interquartile range.

<u>Range:</u>

The range of the data is the difference between the highest and the lowest value in the given set of data.

From the box plot, the highest value is 30 and the lowest value is 15.

Thus, the range of the data is given by

Range = Highest value - Lowest value

Range = 30 - 15 = 15

Thus, the range of the data is 15.

<u>Interquartile range:</u>

The interquartile range is the difference between the ends of the box in the box plot.

Thus, the interquartile range is given by

Interquartile range = 27 - 18 = 9

Thus, the interquartile range is 9.
