What would be the molar concentration of | Class 12 Biology Chapter Biotechnology Principles and Process, Biotechnology Principles and Process NCERT Solutions

Question: What would be the molar concentration of human DNA in a human cell? Consult your teacher.
Answer:

The molar concentration of human DNA in a human diploid cell is as follows:

⇒ Total number of chromosomes × 6.023 × 1023

⇒ 46 × 6.023 × 10­­­23

⇒ 2.77 ×1018 Moles

Hence, the molar concentration of DNA in each diploid cell in humans is 2.77 × 10 23 moles.

The answer is not explained Molar concentration is molarity how can calculate the molarity without knowing the volume of cell?

How this possible actual ans is that 277.058NA OR 2.77058NA(Avogadro's)

6.023 * 10^23 is Avogadro Number

Fair enough But we were supposed to find molar concentration and not no of moles.. we need to divide the number of moles by the volume of a typical cell
