Answer:

Explanation:
1. Find the molar concentration
Assume that we have 100 mL solution.
Mass of NaCl = 0.90 g

2. Find the osmotic pressure
The formula for osmotic pressure (Π) is
Π = icRT
T = (37 + 273.15) K = 310.15 K

it is an endothermic because water can not give off heat it can only take from others like if you were to boil water the water is endothermic and the heat is the exothermic
