The vapor pressure of pure acetone (C3H6O) is 216 torr
svetoff [14.1K]

The mole fraction of acetone (C₃H₆O) is 0.333

<h3>Data obtained from the question </h3>
  • Mole of C₃H₆O = 0.1 mole
  • Mole of CHCl₃ = 0.2 mole
  • Mole fraction of C₃H₆O =?

<h3>How to determine the mole fraction </h3>

Mole fraction of a substance can be obtained by using the following formula:

Mole fraction = mole / total mole

With the above formula, we can obtain the mole fraction of C₃H₆O as follow:

  • Mole of C₃H₆O = 0.1 mole
  • Mole of CHCl₃ = 0.2 mole
  • Total mole = 0.1 + 0.2 = 0.3 mole
  • Mole fraction of C₃H₆O =?

Mole fraction = mole / total mole

Mole fraction of C₃H₆O = 0.1 / 0.3

Mole fraction of C₃H₆O = 0.333

Put the steps in process of photosythensis order
arlik [135]

Answer:

Step 1- CO2 and H2O enter the leaf.

Step 2-  Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2.

Step 3- The electrons move down to enzymes.

Step 4-Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH

Step 5-The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.

Step 6-The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

Step 7-calvin cycle. The second of two major stages in photosynthesis (following the light reactions), involving atmospheric CO2 fixation and reduction of the fixed carbon into carbohydrate.

Hope this helps : D
