How many atoms are present in 0.075 mol of titanium (Ti)?

• A. 6.02 × 10^{21} atoms
• B. 4.52 × 10^{22} atoms
• C. 1.20 × 10^{23} atoms
• D. 8.03 × 10^{22} atoms

Answer: (B)

Verified step by step guidance

1. Understand that 1 mole of any substance contains Avogadro's number of particles (atoms, molecules, etc.), which is \$6.022 \times 10^{23}$ particles per mole.
2. Identify the given quantity: 0.075 moles of titanium (Ti). We want to find the number of atoms in this amount.
3. Use the relationship: Number of atoms = (number of moles) \(\times\) (Avogadro's number). Mathematically, this is \(\text{atoms} = 0.075 \times 6.022 \times 10^{23}\).
4. Set up the multiplication carefully, keeping track of the powers of ten and the decimal numbers separately to avoid errors.
5. After multiplying, express the answer in scientific notation to match the format of the given options.
