A certain protein has a molar mass of 2.38 × 10⁵ G) What is the mass of one molecule of this protein?

Question

Quizplus · Accepted Answer

To find the mass of one molecule of the protein, we need to convert its molar mass (given in grams per mole) into grams per molecule. This can be done by dividing the molar mass by Avogadro's number (6.022 × 10^23 molecules per mole). 
Mass of one molecule = (2.38 × 10^51 g/mol) / (6.022 × 10^23 molecules/mol)
= 3.95 × 10^-19 g/molecule
Therefore, the answer is choice A.
