The answer is: 60.
Tobacco products are made up of thousands of chemicals, including at least 60 known to cause cancer (carcinogens).
Some of carcinogens chemicals are: acetaldehyde, arsenic, radioactive elements (for example polonium-210), nitrosamines, nickel, benzene, polycyclic aromatic hydrocarbons, vinyl chloride.
Smoking tobacco causes at least 15 different types of cancer. For example: mouth, pharynx, larynx, oesophagus, liver, pancreas, stomach, kidney cancer.

Answer:
Piso = 32.17 Torr
Pprop = 5.079 Torr
yprop = 0.1364
yiso = 0.8636
Explanation:
From the question; we can opine that :
- The mole fraction of isopropanol in a mixture of isopropanol and propanol will be 1.
-
The partial pressure of isopropanol will be its mole fraction multiplied by vapor pressure of isopropanol
-
The partial pressure of propanol will be its mole fraction multiplied by vapor pressure of propanol
-
In the vapor, the mole fraction of propanol will be its partial pressure divided by the sum of the two partial pressures
NOW;
When xprop = 0.243; xisopropanol will be 1- 0.243 = 0.757
P°iso = 45.2 Torr at 25 °C so
Piso will be 45.2 × 0.757 = 32.17 Torr
Pprop will be 20.9 × 0.243 = 5.079 Torr
yprop = 5.079/(5.079 +32.17) = 0.1364
yiso = 1-0.1364 = 0.8636
<span>The polar molecules possess the permanent dipole moments caused by slight charge separation in the molecule. In the case of non-polar molecules, the induced electric dipoles are created by an applied electric field causing the slight separation of positive and negative charges in the molecules. The induced electric dipoles are much weaker than permanent electric dipoles.</span>
