1.75 moles SO2 x 6.02x10^23 molecules SO2/mole SO2 = 1.05x10^24 molecules
Dipole-Dipole as SO" is a bent molecule with a dipole momennt (1.62D) due to the electronegativity dfference between S and O. There will also be weaker London dispersion forces due to instantaneous dipoles.
The type of intermolecular force that holds together Oxygen molecules is called a Van der Waal force. Van der Waal forces exist between all molecules and usually have strengths from 1kJmol-1 to up to 50 kJmol-1.
1.12 X10 to the 23rd power molecules SO2
P4O10 is a 'simple covalent molecule' it has a low boiling point because the molecules are held together by weak van der waals forces. such as those in other simple covalent structures; SO2. P4O10 is a larger molecule than SO2 so it has more van der waals forces so it has a higher BP than SO2
SO2 is polar compound.So there are dipole dipole forces.

Dipole-dipole interactions and van der Waals forces of attraction
a. dispersion forces b. hydrogen bonding forces c. dipole-dipole forces
32 g SO2 x 1 mole SO2/96 g x 6.02x10^23 molecules/mole = 2.0x10^23 molecules

72 grams SO2 (1 mole SO2/64.07 grams)(6.022 X 1023/1 mole SO2) = 6.8 X 1023 molecules of sulfur dioxide ============================
parts per million means how many are per million. To get to 1 million from 125,000 you have to multiply by 8, therefore there are 10x8 or 80 molecules so2 per million, therefore 80ppm
The difference between sulphur dioxide and sulphur trioxide is that there are 2 molecules of oxygen present in sulphur dioxide (SO2) and there are 3 molecules of oxygen are present in sulphur trioxide (SO3).
