equvalent wttttttttttttttttttt!!!!!!!

None

eq. wt = mol. wt. / valency

eq wt. of acid = mol. wt. / basicity ------------- (no. of replacable H⁺atoms)

eq. wt of base = mol. wt / acidity ------------- (no. of replacable OH^- atoms)

eq. wt of ion = mol. wt / charge on the ion

eq. wt of salt = mol. wt /total no. of +ive charges

eq. wt by hydrogen disp. method = wt. of element/mol. wt of hydrogen(in that substance) *1

eq. wt by oxygen disp. method = wt. of element/mol. wt of oxygen * 8

eq. wt by chloridedisp. method = wt. of element/mol. wt of chlorine * 35.5

eq. wt by redox process = mol. wt / no. of electrons gained or lost

eq. wt = normality * vol in litres

milli equivalents = normality * vol. in ml = wt. of solute * 1000/eq. wt of solute

%age by wt. = wt. of solute * 1000/wt. of sol

%age by strength = vol. of solute * 1000 / vol. of solution

Cp/ Cv = gamma
= 1.66 (monoatomic)
= 1.40 (diatomic)
= 1.33 (triatomic)

atomic wt. = mol. wt./atomicity

specific gravity of a sol. = wt. of the sol./ vol. of the sol.

how to calculate hardness of water = wt. of CaCO3 / 10^6 g of H2O

eq wt of a subst. in a redox rxn = mol. wt / no. of electrons gained or lost

find Molarity wen %age is given = p * d * 10 / mol. wt
