Question

Which of the following is true of 12.01 grams of carbon (C)? Mark all correct answers.

This is 602,200,000,000,000,000,000,000 carbon atoms.
This is 1.000 mole of C.
This is 6.000 moles of C.
This is 6 carbon atoms.
This is the mass in grams of one carbon atom.

Answer 1

12.01 grams of carbon represent 1.000 mole of carbon and equate to 6.022 × 10²23 carbon atoms, as per Avogadro's number.

Step-by-step explanation:

Regarding 12.01 grams of carbon (C), the following statements are true:

• This is 1.000 mole of C since one mole of carbon has a mass of 12.0 grams, per the atomic mass unit (amu) indicated on the periodic table and considering that it is nearly pure 12 C.
• This amount corresponds to 6.022 × 1023 carbon atoms, as defined by Avogadro's number for the number of particles in a mole.

Other statements mentioned are false because they either misrepresent the number of moles, atoms, or the mass of a single carbon atom.
