The enthalpy of vaporization of water is 2,257,000 J/kg. If I have a 1 kg sample, how much energy is needed to boil all of it
1 answer:
Answer:
2257000 J
Explanation:
Applying,
Q = Cₓm.................. Equation 1
Where Q = amount of energy need to boil the water, Cₓ = Enthalpy of vaporization of water, m = mass of water.
From the question,
Given: Cₓ = 2257000 J/kg, m = 1 kg
Substitute these values into equation 1
Q = 2257000×1
Q = 2257000 J
Hence the energy needed to boil all of the water is 2257000 J

Answer:
59.16 g
Explanation:
Mass = Density × Volume
= 3.4 g/mL × 17.4 mL
= 59.16 g or
59.2 g (rounded to three significant figures) or
59 g (rounded to two significant figures)
