Answer #1

Strong electrolytes(SE) are the one which dissociates completly and give more conductance & its value is more than 1

Weak electrolytes(WE) are the one which dissociates partially and giveless conductance & its value is less than 1

Non-electrolytes(NE) are the one which does not give any conductance so its value is ZERO.

From the given table ,

B & E have conductance 7.2 & 2.6 respectively & these values are more than 1 so these are strong electrolytes.Therefore there are totally two(2) are SE.

A,D,F & G have conductance 0.4 , 0.2 , 0.6 & 0.7 respectively & these values are less than 1 so these are weak electrolytes.Therefore there are totally four(4) are WE.

C has conductance value '0'(ZERO) so it is a non-electrolyte.Therefore there is only one(1) NE.
