    Remember there are three equations relating to moles. they are:- 

    moles(solids) = mass(g) / Mr 

    moles (liquids)= [conc] x vol(mL) / 1000

    moles(gases) = PV/RT

    These three equations are mathematically interchangeable.  e.g. 

    mass(g)/Mr = PV/RT 

    However, the conversion fctor for liquids is 

    moles = [conc] x vol(mL) / 1000

    NB The '1000' is needed to convert 'mL' to 'L/dm^3' because conc'n is quoted in 'moles dm^-3' or 'mole L^-1'. 

    NB 'dm^3 and 'L' are the same volume with different names.

    As previous responders answered, it's the molar volume; for gases, it's calculated using the ideal gas equation:

    PV = nRT

    Rearrange that to:

    n/V = P/(RT)

    (P, V, T, and R are in appropriate units to give moles/L)

    For liquids and solids, it's calculated from the density (p [Greek rho], in g/mL)) and molecular (or formula) weight (MW, in g/mole) for a given substance:

    Molar Volume (mole/L) = (p/(MW)) x (1000 mL/L)

    Ideal Gas Law: PV=nRT

    n is moles, R is gas constant (use the correct one!),

    T is the temp in K (C+273.15)

    V is the volume in Litres

    If we're talking about the volume of a gas, the requested relationship is called the molar volume.

    At 1 atm and 0°C,

    22.4 L = 1 mole

    [If we're talking about liquids or solids there is no direct conversion factor between  volume and moles.  The conversion can be made, but it is a multi-step process which requires more than one factor.]

    There isn't any. Mole is a number , like million is

    How many moles of molecules fit in a liter depends on the density of the substance, aka the size and shape of the molecules
