Answer : The amount of salt present in the tank initially are, 50 kg

Explanation : Given,

Mass of salt in the tank = 50 kg

Mass of water in the tank = 1000 L

Rate of flow of water in the tank = 6 L/min

Rate of flow of solution in the tank = 3 L/min

Now we have to determine the amount of salt present in the tank initially.

As per question, there are 50 kg of salt present in the tank initially in 1000 L of water.

Thus, the amount of salt present in the tank initially are, 50 kg

You can use P1V1/T1 = P2V2/T2 but since pressure is constant is becomes V1/T1=V2/T2

V1=0.5 L
T1=203 K
T2=273 K
V2=unknown

0.5L/203 = V2/273
V2= 0.67 L so C

Hope this helps :)

What is the change in temperature when 75 grams of water releases -2657 J of energy? The specific heat of water is 4.18 J/g°C
Naily [24]
I think the answer for this is 4702.5 J/g*k Depending on if it is water as a solid liquid or gas. I used water as a liquid when I solved it. J=(75g)(4.18 J/g*k)(15K)
