<h3>Solution:</h3>

$\text{mass of Pb = 1.15 × 10²⁴ Pb atoms} × \frac{\text{1 mol Pb}}{\text{6.022 × 10²³ Pb atoms}} × \frac{\text{207.2 g Pb}}{\text{1 mol Pb}}$

$\boxed{\text{mass of Pb = 396 g}}$

Taking into account the Newton's second law, the correct answer is option A. F = 9.68 N right

In first place, acceleration in a body occurs when a force acts on a body.

Newton's second law states that a force will change the speed of an object because the speed and/or direction will change. These changes in velocity are called acceleration.

So, Newton's second law defines the relationship between force and acceleration mathematically. This law says that the acceleration of an object is directly proportional to the sum of all the forces acting on it and inversely proportional to the mass of the object

Mathematically, Newton's second law is expressed as:

F= m×a
