Answer:
Osmotic pressure is: 2,01 atm
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). <em>0,078M</em>
R is ideal gas constant (0.08206 L atm mol⁻¹ K⁻¹, ).
T is the temperature on the Kelvin scale. 41°C +273,15 = 314,15 K
Replacing you have:
π = 0,078M×0.08206 L atm mol⁻¹ K⁻¹×314,15 K
<em>π = 2,01 atm</em>

Answer:
the functional group in ethyl alcohol is :OH(hydroxyl group)
Explanation:
the principle of solubility or miscibility is :''like dissolves like'' which means compounds that are similar dissolves each other,Ethanol or ethyl alcohol mixes or interacts with water by forming hydrogen bond with water,since both water and ethyl alcohol are polar compounds.
