How will molar conductivity vary with concentration or temperature?
molar conductivity involves concentration of electrolyte also....but electrolytic conductivity doesn't
What causes entropy to change when a solute dissolves in a solvent?
The solute becomes less ordered. (apex)
Is the molar kinetic energy of chlorine gas equal to greater to or less than the molar kinetic energy of nitrogen at 25 degrees Celsius?
equal to
What is the mass in grams in 1.00 molar mass FE?
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
How do you convert from number of particles to moles?
You must first calculate the molar mass of the substance. To do so, you add up the molar masses of all the elements that make up the compound, multiplied by the number of atoms of that element in one molecule of the substance. For example, AgNO3 has a molar mass of about 169.8 amu. In one molecule of AgNo3, there is one atom of Silver (molar mass 107.8), one atom of Nitrogen (molar mass 14), and three atoms of Oxygen (molar mass 16). Multiply the molar mass of Silver by the number of Silver atoms (1), multiply the molar mass of Nitrogen by the number of Nitrogen atoms (1), multiply the molar mass of Oxygen by the number of Oxygen atoms (3), add the numbers up and you have the molar mass of the substance (169.8). Step 2 is easy. To convert from grams to moles, you divide the number of grams by the molar mass (units for molar mass are grams per mole, so dividing by molar mass cancels the grams). To convert from moles to grams, you multiply by the molar mass.
What is the relationship between molar mass and evaporation rates?
They are inversely related. This means that as molar mass increases, the rate of evaporation decreases. This is because as molar mass increases, the intermolecular bonds also get stronger, and it is more difficult to break those bonds and for liquid molecules to jump into a gaseous state.
Which is more volatile hydrocarbon C15H32 or C8H18?
C8H18 bcz volatility depends upon intermolecular forces and alkanes have van der wall f.o.a and this force depends upon molar mass..Since c8h18 has lower molar mass so the force is less and intermolecular attraction is less.. So it can easily get vaporized . Therefore c8h18 is more volatile..

Why does the molar conductivity of weak acid decrease as the concentration increases?
For a weak acid (or base), as the concentration increases, the % ionization/dissociation decreases. This leads to fewer ions in solution, and hence the molar conductivity decreases.
WHY dilution increase conductivity?
Molar conductivity is what increases dilution. It is the conductivity of an electrolyte solution.
Why we called as excess molar volume?
There are idealand non-ideal mixtures. In the second case the intermolecular forces between the different molecules of the mixture are less (Positive deviations from Raoult's Law) or more (Negative deviations from Raoult's Law) strong than they are in the pure liquids.This difference in the intermolecular forces causes a expansion (less strong) or retraction (more strong) of the volume after the mixing, this is the cause of the excess molar volume.The excess molar volumes VE can be calculated by using measured experimental densities and correlated by the Redlich−Kister type equation.
What type of mole is speckles in G-force?
A MOL-ar! get it? like molar? mole-ar
Creep in amalgam dentistry is?
The biting force acting in the premolar and molar region in the oral cavity.
How does the molar absorptivity depend upon the concentration mole per L of the dissolved solute?
Molar absorptivity is completely independent of concentration of a substance as Molar absorptivity is represented by epsilon and is a constant. Absorbance of light is what is dependent upon concentration and will go down as concentration goes down and increase as concentration increases.
What determines the strength of dispersion forces?
London dispersion forces are dependent on the motion of electrons, their strength increases with the number of electrons in the interacting atoms or molecules. This means that London forces increase as the atomic or molar mass increases.
What is the literature value for the melting point of aspirin?
melting point- 136 degree C boiling point- 140 degree C
What is molar conductivity at infinite dilution?
Molar conductivity at infinite dilution is when molar conductivity is limited. Molar conductivity is when electrolyte conductivity is divided by molar concentration.
