Answer:
<h2>62,560 kg</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
volume = 34,000 L
density = 1.84 kg/L
We have
mass = 1.84 × 34,000 = 62,560
We have the final answer as
<h3>62,560 kg</h3>

Answer:
1672 J
Explanation:
We are supposed to find out the energy released by water when cooled from 50° C to 30°C .
We have the relation that ,
H=msΔT
Information is given that s=4.18 J/ g*°C ,
m=20.0 g,
and ΔT is -20° C.
Hence by substituting we get,
H=-20*20*4.18
(minus symbol represents that energy is being released)
1672 J is release when water is cooled from 50° C to 30°C .
