The mass of one atom or molecule of a substance is given in atomic mass units, also called Daltons (abbreviated D or Da). Thus one molecule of water has a mass of 18.015 atomic mass units, or 18.015 Daltons. The atomic mass unit is defined such that one mole of water weighs 18.015 g. Suppose a protein has a mass of 64 192 Daltons (or 64.192 kDa). What would be the mass of one mole of this protein? O A. A protein of 64 192 Da has a molar mass of 3.866 x 1028 g/mol. OB. A protein of 64 192 Da has a molar mass of 1.0 g/mol. O C. A protein of 64 192 Da has a molar mass of 18.015 g/mol. ● D. A protein of 64 192 Da has a molar mass of 64.192 g/mol. O E. This question can't be answered without knowing the number of atoms in the protein. O F. A protein of 64 192 Da has a molar mass of 6.4192 x 10-² g/mol. O G. A protein of 64 192 Da has a molar mass of 3.866 x 10²5 g/mol. OH. A protein of 64 192 Da has a molar mass of 64 192 g/mol.

Question
The mass of one atom or molecule of a substance is given in atomic mass units, also called Daltons (abbreviated D or Da). Thus one molecule of water has a mass of
18.015 atomic mass units, or 18.015 Daltons. The atomic mass unit is defined such that one mole of water weighs 18.015 g. Suppose a protein has a mass of 64 192
Daltons (or 64.192 kDa). What would be the mass of one mole of this protein?
O A. A protein of 64 192 Da has a molar mass of 3.866 x 1028 g/mol.
B. A protein of 64 192 Da has a molar mass of 1.0 g/mol.
C. A protein of 64 192 Da has a molar mass of 18.015 g/mol.
D. A protein of 64 192 Da has a molar mass of 64.192 g/mol.
E. This question can't be answered without knowing the number of atoms in the protein.
F. A protein of 64 192 Da has a molar mass of 6.4192 x 10-2 g/mol.
G. A protein of 64 192 Da has a molar mass of 3.866 x 1025 g/mol.
H. A protein of 64 192 Da has a molar mass of 64 192 g/mol.
