For molecules of similar polarity, larger molecular masses would equate to higher boiling points. This is because molecules with larger masses would have stronger intermolecular van der Waals forces.

The bigger the mass the higher the boiling point.

If the mass increases with the volume (ie if the density remains the same) then the boiling point remains constant. If the volume remains contstant with rising mass (ie greater density) then the boiling point increases.

we can determine the molecular weight from landsberger experiment for elevation of boiling point by using the formula M2=(KBW2)*1000/T'W1 where M2=molecular mass Kb=ebullioscopic constant or molal boiling point constant W2=mass of solute W1=mass of solvent T'=change in temprature

the main applicative use of freezing point depression and boiling point elevation is to calculate the molecular mass of a non volatile solute in a pure solvent.

SO2 has a higher boiling pt because it has a greater molecular mass, SO2 is a pola r molecule which forms dipole-dipole forces which increases the boiling point

nitrogen has lower mass and weaker molecular forces of attraction

Actually, for its molecular mass, water has a very high boiling point because the moleculaes stick together due to hydrogen bonding.

The molecular mass of iodobutane is higher so density and boiloing point also higher than chlorobutane.

The gram molecular mass of the molecule must be measured by some independent method such as freezing point depression or boiling point elevation. Then the factor by which to multiply all of the subscripts in the empirical formula to get the molecular formula is the closest integer to the ratio of gram molecular mass to the gram molecular mass of a single unit of the empirical formula.

There are three properties that can be used and they are the boiling point elevation, freezing point depression, and osmotic pressure. The molar mass is equal to mass of the unknown divided by the moles of the unknown.

Yes, the molecular mass of propane is 44 while that of butane is 58, higher is the molecular mass of an alkane higher would be the boiling point therefore less would be the volatility.

The larger the molecular mass the higher the melting point will be and the longer it will take to melt

The boiling point is not changed.

The boiling point constant of water is: kb = 0.512. The equation for boiling point elevation is (change in Temp) = kb * Bb where Bb is the molality of the solution taking dissociation into account.

Predominantly its higher molecular mass. The higher mass of a molecule of C5H12 requires more energy to cause it to move fast enough to escape its intermolecular bonding than does the lower mass C2H6 molecule. The intermolecular bonding itself may be stronger in the higher molecular mass molecule, but this is relatively minor compared with the difference in molecular mass.

Vaporization (in mass, at the boiling point) or evaporation (on the surface and under boiling point).

Hydrogen bonding. The high boiling point of water, approximately 100 degrees Celsius at sea level, is due to the high number of hydrogen bonds each water molecule can have relative to its low molecular mass.

mass, volume, density, melting point, boiling point

The more is the number of carbons in the alkane, the more is its boiling point.REASON:- As the number of carbon increases, the becomes the molecular mass. And the more is the molecular mass, the greater becomes the surface area which increases the van der Waal force of intermolecular attraction thereby increasing the boiling point of the alkane.NOTE:- Among isomers (of the same alkane), the structure which have more # of side chain has less BP because more the # of side chains are present, more will the structure will be closer to the shape of a sphere, therefore will have smaller surface area.-by spd831
