Answer:


W=8.93\cdot 10^(-30)\ N
\mathbf{W=8.93\cdot 10^(-30)\ N}

Step-by-step explanation:

Mass and Weight

The mass of an object is a measure of the object's amount of matter it contains. It's expressed in Kilograms or similar units.

The weight of an object is a measure of the force exerted on the object by gravity. It's often expressed in Newtons or similar units.

The formula to calculate the weight of an object with known mass m is:

W = m.g

Where g is the acceleration of gravity in the place it's located. We are given the mass of an electron:


m=9.109\cdot 10^(-31)\ Kg

On Earth, the acceleration of gravity is:


g=9.8\ m/s^2

Thus, the weight is:


W =9.109\cdot 10^(-31)\ Kg*9.8\ m/s^2


\mathbf{W=8.93\cdot 10^(-30)\ N}
