Alright, let's address each part of the question individually:

### Molar Mass Equivalent
1. Molar Mass Equivalent to [tex]$6.022 \times 10^{23}$[/tex]:
- This number, [tex]\( 6.022 \times 10^{23} \)[/tex], is known as Avogadro's number. It's the number of atoms, molecules, or other particles in one mole of a substance.
- Therefore, the molar mass in grams per mole can be associated with this number.

### Negatively Charged Electrode
2. Negatively Charged Electrode (B):
- The negatively charged electrode in an electrical circuit, particularly in electrochemical cells, is called the cathode when dealing with the source of an electric current. But typically, the cathode is the negative terminal in a battery or in electrolysis.
- In the context of this question, 'B' refers to this negatively charged electrode.

### Mass in Grams of 1 Mole
3. Mass in Grams of 1 Mole of a Substance (C):
- The mass of one mole of a substance is indeed its molar mass, typically expressed in grams per mole.
- The molar mass value is inherently tied with Avogadro's number in that it signifies the amount of physical matter corresponding to [tex]\( 6.022 \times 10^{23} \)[/tex] molecules or atoms.

### Conclusion
So, to summarize:
- Avogadro's number [tex]\( 6.022 \times 10^{23} \)[/tex] refers to the number of atoms, molecules, or particles in one mole of a substance.
- 'B' denotes the negatively charged electrode.
- 'C' refers to the mass in grams of one mole of a substance, which is its molar mass.

The answers to the given questions are:
- [tex]\( 6.022 \times 10^{23} \)[/tex]
- B: Negatively charged electrode
- C: Mass in grams of one mole of a substance
