what is eqiuvalant mass
Answers
Answer:
The idea of equivalent mass to compare chemically different elements! Atoms combine with each other to form chemical compounds, such that the elements are always present in definite proportions by mass and this property can be used to make chemically different molecules with different mass, equal
Equivalent mass: The number of parts by mass of a substance that combines with or displaces 1.008 parts by mass of hydrogen or 8.0 parts of oxygen or 35.5 parts of chlorine is called its equivalent mass (EM).To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid's molar mass by the number of protons.
