31. Solving a chemistry problem

37. How many liters of ammonia at 289 K and 1.01∙105 Pa can be adsorbed on the surface of 45 g of active carbon if the entire surface is completely covered with NH3? Surface 1g active charcoal 1000m2. The diameter of the NH3 molecule is 3∙10-8 cm. The molecules touch each other in a plane so that the centers of four adjacent spheres are located at the corners of the square.
