20 gm of an acid furnishes 0.5 mole or HNO3+ iONS in its aq solution .the value of 1 eqyivalent if the acid will be
To find the value of 1 equivalent of the acid, we need to determine the molar mass of the acid.
Given that 20 grams of the acid furnishes 0.5 moles of HNO3+ ions, we can use this information to find the molar mass of the acid.
The molar mass (M) can be calculated using the formula:
M = (mass) / (moles)
So, in this case, we have:
M = 20 gm / 0.5 mol
M = 40 gm/mol
To find the value of 1 equivalent of the acid, we need to divide the molar mass by the valency of the acid. The valency is the number of hydrogen ions (H+) that are produced by 1 molecule of the acid.
In this case, HNO3 is the acid. The valency of HNO3 is 1 because it produces 1 H+ ion per molecule of the acid.
Therefore, the value of 1 equivalent of the acid will be:
Value of 1 equivalent = Molar mass / Valency
Value of 1 equivalent = 40 gm/mol / 1
Value of 1 equivalent = 40 gm/equivalent
So, the value of 1 equivalent of the acid is 40 gm/equivalent.
