Final answer:
To find the number of titanium atoms in 5 moles, multiply the moles (5) by Avogadro's number, resulting in 3.011 x 10²³ atoms of titanium, which corresponds to option B.
Step-by-step explanation:
The question asks about the number of titanium atoms in a specified quantity. Using the provided reference, we can determine that when 5 moles of a substance are given, we calculate the number of atoms by multiplying the number of moles by Avogadro's number (6.022 x 10²³ atoms/mol). Therefore, for 5 moles of titanium, the calculation would be 5 mol × 6.022 × 10²³ atoms/mol, which equals 3.011 x 10²³ atoms of titanium, matching option B in the original question.
