If you know the mass of an object you can calculate its weight with the formula
Vikki [24]
Answer: True

The formula of weight is w = mg, where m is the mass and g is the acceleration of gravity. If you want to calculate an object's weight, you need to know the two components: mass and gravity. 

You only need to know the mass of the object because the acceleration of gravity is ALWAYS (assuming the object is on Earth) 9.8 m/s^2.

What is a chemical formula?
krek1111 [17]

Answer:

A. An identification of the atoms in a molecule

Explanation:

The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.

Therefore, a chemical formula allows us to identify atoms that are within a molecule.

A molecule is a covalent compound that has discrete or separate units.

For example;

         HCl represents 1 mole of hydrogen chloride molecules consisting of 1 mole of hydrogen atoms and 1 mole of chlorine atoms.
