Final answer:
The sample that contains a total of 6.0x10²³ particles is option B) 1 mole of CO2 molecules.
Step-by-step explanation:
The sample that contains a total of 6.0x10²³ particles is option B) 1 mole of CO2 molecules.
In chemistry, a mole is a unit used to measure the amount of a substance. It represents Avogadro's number, which is approximately 6.022 x 10²³ particles per mole. Each mole of a substance contains this same number of particles, regardless of whether they are atoms, ions, or molecules.
Therefore, since option B states 1 mole of CO2 molecules, it will contain 6.0x10²³ CO2 molecules.
