Answer:
The grams of chlorophyll you need are 11,1 g
Explanation:
Osmotic pressure is the minimum pressure that you needs to be apply to a solution to prevent the inward flow of its pure solvent across a semipermeable membrane. The formula of osmotic pressure is:
π = M×R×T
Where:
M is molar concentration of dissolved species (units of mol/L).
R is ideal gas constant (0.08206 L atm mol⁻¹ K⁻¹, ).
T is the temperature on the Kelvin scale.
In the problem you have:
1,19 atm = M×0,08206 L atm mol⁻¹ K⁻¹×298K
M = 0,048 M
Thus, the grams of chlorophyll you need are:
0,048 × 0,258 L × = <em>11,1 g</em>

Answer:
Milk is essentially a colloidal dispersion of fat in water. ... However, the fact remains that the fat and water components cannot be mixed together from a solution. There are therefore, two distinct immiscible liquid phase's present, which is why it is a heterogeneous mixture.
