In order to measure the mass of a body, it is necessary to find a standard mass or a combination of standard masses whose weight exceeds that of a body at the same place on earth. The device employed for this purpose is called a balance.
A beam balance compares 2 weights. A physical balance compares a weight to a known referance (ie spring

Screws help to level beam of physical balance so that both pans can be balanced before putting mass and weight in both pans. WAHEED
The molar mass is not needed to balance a chemical reaction.You need to know the chemical formulas of reactants, the possible formulas of products, valences of elements and ions, general principles of chemical reactions, some chemical and physical properties of substances involved in the reaction.

Principles of MAÁT: Truth, Justice, Harmony, Balance, Order, Reciprocity, Propriety
the physical balance is an instrument which is used to measure the mass of object
Actual balance is the real balance while avialable balance is the physical balance
the five alternative principles are: 1) Regularity 2) Specificity 3) Balance 4) Progression 5) Recovery
