Sorry if this is incorrect. To my understanding this is the correct answer.
Answer:It would depend on the eluent solvent what we use ,If we would use a polar solvent than B will be appear first followed by c and then A on the chromatography strip.
If we use non-polar eluent solvent than A will be separated first followed by C and thenB on the chromatography strip.
Explanation:
Separation using paper chromatography is dependent upon the polarity of various pigments .
A polar pigment would move ahead in case of polar solvent used and a non-polar pigment would move ahead when we use a non-polar solvent.
So separation would occur in order of polarity of various pigments in a given solvent.
The amount of distance travelled by each component (or pigment or spot) can be calculated using the formula for retention factor:
Rf= Distance travelled by pigment spot or solute/Distance travelled by eluent solvent
Rf= Retention factor
Retention factor is basically the ratio of distance tarvelled by the pigment or spot to the ratio of distance travelled by the solvent.
Answer;
Molar mass of water is 18.02 g/mol
Explanation;
-Molar mass of a compound is determined by adding the relative atomic mass of each atom present in the compound. Molar mass of one mole of a compound, it is the weight in grams of 6.02 × 1023 atoms or molecules.
-Therefore; to calculate the molar mass of Water (H2O); we first know the RAM of hydrogen and oxygen which are; H=1.01 and O= 16.00
Since there is two atom of hydrogen and one atom of oxygen in water;
Then; the Molar mass of water will be; 2×1.01 + 1 ×16 = 18.02 g/mol
