Rachel has a sample containing 2 moles of carbon. how many atoms of carbon are in this sample? a. 2.044 × 1023 atoms b. 6.022 × 2023 atoms c. 1.204 × 1024 atoms d. 6.022 × 1046 atoms

Answer is: c. 1.204 × 10²⁴ atoms of carbon.

n(C) = 2 mol; amount of substance of carbon.

Na = 6.02·10²³ 1/mol; Avogadro constant (the number of constituent particles, in this example atoms, that are contained in the amount of substance given by one mole).

N(C) = n(C) · Na.

N(C) = 2 mol · 6.02·10²³ 1/mol.

N(C) = 12.04·10²³ = 1.204·10²⁴; number of carbon atoms in a sample.

Answer is C

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
