A butterfly rests on a leaf floating on the surface of a pond. The butterfly then starts moving to the tip of the leaf at a speed of 5 cm s -1 relative to the water. The leaf，in accordance with the principle of conservation of momentum，moves at 3 cm s -1 relative to the water in the opposite direction. If the mass of the leaf is 8g，determine the mass of the butterfly.
