Answer b I think so sorry if not is
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:
A
D
E
and maybe C I'm not sure on that one.
Explanation:
The force equal but opposite to the one shown is : ( D ) The force that the branch applies to the kitten
<h3>Opposite and equal forces </h3>
The force of gravity/weight of an object is equal and opposite to the reactive force because it cancels the effect of the weight of the object on the surface. In option D the force that the branch applies to the kitten resting on it is equal and opposite to the weight of the kitten.
Hence we can conclude that The force equal but opposite to the one shown is The force that the branch applies to the kitten.
