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.
