Mass and Weight aren't the same thing. Mass is considered as one of the attributes of matter. This is true because matter is defined as anything that has mass and occupy space.
From the above introduction, we can conclude that matter has two main attributes or characteristics. These are:
Mass is the amount of matter a body or anything has. Think of it as the entire composition of anything.
For instance, everything you are composed of (from the top of your hair to your toe nails, including your internal organs) will account for your mass. For this reason, your mass will be significantly different from that of a newly born child.
Matter will always take up space no matter how small it is. This is true because some instances of matter can be microscopic; for example, bacteria, protists and virus.
Note: A space completely void of matter is referred to as a vacuum. A vacuum environment barely exist naturally, rather they are prepared for medical and scientific reasons.
Mass is the amount of matter in anything and it will always remain constant (the same) for that specific thing all over the universe.
Consider the instance below:
Let's assume that one mole of copper has a mass 100g. If you travelled with this copper (one mole) to another country or to the moon or to planet jupiter, it will always have the mass of 100g because it's the same amount of copper (one mole).
The above instance is true because pure copper will always have the (exact) same type of atoms (and that's copper atoms).
Note: Gravitational force will always act on mass. In fact it is the action of gravity on the mass of a body that gives rise to weight. You can therefore think of weight as gravity acting on mass.
Below is an image that show the concept of Mass and Weight:
Weight is a function of gravity. This means that gravity accounts for our weight.
Weight can be defined as the force exerted on a body by gravity. Think of gravity as the force that pull things downwards.
One mole of copper will have different weights on the moon, earth and jupiter simply because the moon and planets all have different gravitational pull acting on them.
Jupiter has a stronger gravity than earth and earth has a stronger gravity than the moon. This is a fact because:
The bigger a body, the larger its force of gravity.
Based on the above explanations, one mole of copper will weigh more in jupiter and least on the moon. However, it's mass will always remain constant (the same) regardless the location.

Amazing facts in Basic Science
Rasceta is the name given to the lines on your ✋ palm ✋
Goats have rectangular pupils in their eyes.
Think of the pupil as a hole located in the centre of the iris of the eye.
Note: To get an idea of an iris; when one is said to have blue eyes, it's because the iris is blue

The eyebrow is an area of dense, delicate hair just above the eye.
Eyebrows perform two main functions:
Eyebrow modified in the form of Nike.

Note: Eyebrows can also be modified to enhance beauty; especially female beauty.
All fruits have seeds. There is nothing like a naturally occurring seedless fruit. Even banana, coconut and pineapple have all got seeds.
Weight can be defined as the force of gravity acting on an object. If you traveled to space, you would be weightless because there isn't any force of gravity acting there. We all have weight on earth becasue the force of gravity acts here. Weight is measured in Newton
Massis the amount or quantity of matter/material contained in a body, For instance, everything you are composed of, both from within and outside will make up your mass. Mass is constant throughout the universe. You will have the same mass on earth and moon. Mass is measured in gram or kilogram. Mass is quite different from weight.
Matter is anything that has mass and occupy space. Matter can exist in four states namely:
