Answer:
1.9 kg
Step-by-step explanation:
Empty container: 3/10 kg = 0.3 kg
Container half filled: 1 1/10 kg = 1.1 kg
Mass of water that fills it halfway: 1.1 kg - 0.3 kg = 0.8 kg
Mass of water that fills it completely: 2 * 0.8 kg = 1.6 kg
Mass of container completely filled with water: 0.3 kg + 1.6 kg = 1.9 kg
