Equivalent (chemistry)

An equivalent (symbol: officially equiv unofficially but often Eq) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount of another substance in a given chemical reaction It is an archaic unit of measurement that was used in chemistry and the biological sciences in the era before researchers knew how to determine the chemical formula for a

What is the mass of HCl in a 500 mL sample of 6 0 M

109 g of HCl Molarity is represented by the following equation: In our case we already have the molarity and the volume of solution However the volume does not have the proper units since it is given in terms of milliliters instead of liters We can convert 500 mL into liters by using the conversion factor 1000mL = 1L When 500 mL is divided by 1000 mL/L we obtain a volume of

Equivalent mass of acid − Estimated mass Calculation

Equivalent Mass is the amount of substance that combines with or displaces 8 0 g of oxygen (or 1 008 g of hydrogen) usually expressed in grams for acid/base reactions one equivalent donates or receives a mole of protons and the equivalent weight is the ratio of the molecular weight to the number of protons involved in the reaction
