Answer is Sodium Hydroxide.
Answer:
4.88 kg
Explanation:
Amount of energy generated in 1 hour of exercise = 5500 kJ
Thus,
Amount of energy generated in 2 hours of exercise = 5500*2 kJ
So,
Amount of energy generated in 2 hours of exercise = 11000 kJ
Heat of vaporization of water = 40.6 kJ/mol
40.6 kJ of energy is required to vaporize 1 mole of water
Also,
11000 kJ of energy is required to vaporize (1/40.6) * 11000 mole of water
Moles of water = 270.936 moles
Molar mass of water = 18 g/mol
Mass = Moles * Molar mass = 270.936 * 18 g = 4876.8473 g
Also,
1 g = 0.001 kg
So, mass of water = 4.88 kg
