Answer 1

The molar mass is the mass of which of the following?

The mass of a substance per mole and the g/mol of a substance is correct.

The molar mass of a substance is the mass per mole of its entities (molecules, atoms, ions, etc)

6.0221x10^23 particles of a substance is also correct. The mole contains 6.022 x 1023 entities. The number of entities in a mole is called Avogadro's number.

Answer:

The mass of a substance per mole

The g/mol of a substance

6.0221 x 10^23 particles of a substance
