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

Point o is the center if the circle. what is the value of x? mn and mp are tangent to
mrs_skeptik [129]

Answer:

x=66

Step-by-step explanation:

Since  MN and MP are tangent to circle O, they create 90° angles at the points of intersection.

We also know that this is a quadralateral, so the interior angles add up to 360.

We can make an equation with this information.

114+90+90+x=360

294+x=360

x=66
