The water equivalent of a calorimeter is 10 g and it contains 50 g of water at 15$$^\circ$$C. Some amount of ice, initially at $$-$$ 10$$^\circ$$C is dropped in it and half of the ice melts till equilibrium is reached. What was the initial amount of ice that was dropped (when specific heat of ice = 0.5 cal gm

^{$$-$$1}$$^\circ$$C^{$$-$$1}, specific heat of water = 10 cal gm^{$$-$$1}$$^\circ$$C^{$$-$$1}and latent heat of melting of ice = 80 cal gm^{$$-$$1}) ?2
