Answer:
7.99 × 10⁸ atoms
Explanation:
The diameter of Molybdenum atom is 418pm = 0.000000000418m
therefore to determine number of Mo Atoms that'll be required =
0.334 ÷ 0.000000000418 = 7.99 × 10⁸ atoms
Mass of one Mo atom = 1.59×10⁻²² g
Mass of 7.99 × 10⁸ atoms that'll be required = 1.59×10⁻²² × 7.99 × 10⁸ =
12.7041 × 10⁻¹³g.
