Final answer:
Carbon-14 has 8 neutrons.
Step-by-step explanation:
The number of neutrons in an atom is determined by subtracting the atomic number (number of protons) from the mass number. Carbon-14 (¹⁴C) has a mass number of 14 and an atomic number of 6. Therefore, to find the number of neutrons, subtract 6 (atomic number) from 14 (mass number). So, carbon-14 has 8 neutrons.
Given that the question is asking for the number of neutrons in 3.01 x 10^23 atoms of carbon-14, we can multiply the number of atoms by the number of neutrons per atom (8). So, the total number of neutrons would be 8 x 3.01 x 10^23, which is 2.408 x 10^24 neutrons.
