Question

The temperature of mixture of two liquids doesn't depend on their masses this statement wrong or right

Answer 1

The temperature of two liquids which are miscible is independent on their masses. This is true in that being that the two liquids mix the net effect may be that they mix by evolution of heat in which case the temperature will be higher.

When the two liquids mix by absorption of heat, their temperature will reduce.

Due to these  two explanations, we cannot say that the temperature of the miscible liquids is depended on their masses.
