Answer:
A pressure value more than 0.012 atm must be applied to the apparatus at 20.0°C to produce pure water.
Explanation:
When pressure more than the value of osmotic pressure of the solution is applied to the solution then water will move out from the solution which is termed as reverse osmosis.
Given that 1.70 grams of sucrose was present in 1 L of solution.
Moles of sucrose present in 1 liter of solution =
C = 0.004971 mol/L
Temperature of the solution = T = 20.0°C = 20.0+273 K = 293 K
Osmotic pressure of soluion =
A pressure value more than 0.012 atm must be applied to the apparatus at 20.0°C to produce pure water.
Answer:
Explanation:
To find the weight (W) of the pond contents first we need to use the following equation:
(1)
Where m the mass and g is the gravity
Also, we have that the mass is:
(2)
Where ρ is the density and V the volume
We cand calculate the volume as follows:
(3)
Where L is the length, w is the wide and d is the depth
By entering equation (2) and (3) into (1) we have:
Therefore, the weight of the pond is 6.65x10⁶ lbf.
I hope it helps you!
