Departure Hall 2 consists of Piers D and E.
Pier D is the largest pier and has two levels. The lower floor houses non-Schengen flights and the upper floor is used for Schengen flights. By using stairs, the same jetways are used to access the aircraft. Schengen gates are numbered beginning with D-59; non-Schengen gates are numbered from D-1 to D-57.
Pier E is a dedicated non-Schengen area and has 14 gates. It is typically home to SkyTeam hub airlines Delta Air Lines and KLM, along with other members, such as China Airlines and China Southern Airlines. Other Middle Eastern and Asian airlines such as EVA Air, Etihad Airways, Iran Air and Air Astana also typically operate out of Pier E.
Amsterdam Airport Schiphol is also easily accessible by bus, as many services call or terminate at the bus station located outside in front of the terminal building.
The Taiwanese EVA Air provides private bus services from Schiphol to Belgium for its Belgium-based customers. The service, which departs from and arrives at bus stop C11, goes to Sint-Gillis, Brussels (near the Brussels-South (Midi) railway station) and Berchem, Antwerp (near Antwerp-Berchem bus station). The service is co-operated with Reizen Lauwers NV.
It is common practice in laboratories to make a solution directly from its constituent ingredients. There are three cases in practical calculation:
Case 1: amount of solvent volume is given.
Case 2: amount of solute mass is given.
Case 3: amount of final solution volume is given.
In the following equations, A is solvent, B is solute, and C is concentration. Solute volume contribution is considered through ideal solution model.
Case 1: amount (mL) of solvent volume VA is given. Solute mass mB = C VA dA /(100-C/dB)
Case 2: amount of solute mass mB is given. Solvent volume VA = mB (100/C-1/ dB )
Case 3: amount (mL) of final solution volume Vt is given. Solute mass mB = C Vt /100; Solvent volume VA=(100/C-1/ dB) mB
Case 2: solute mass is known, VA = mB 100/C
Case 3: total solution volume is known, same equation as case 1. VA=Vt; mB = C VA /100
Example: Make 2 g/100mL of NaCl solution with 1 L water Water (properties). The density of resulting solution is considered to be equal to that of water, statement holding especially for dilute solutions, so the density information is not required.
mB = C VA =( 2 / 100 ) x 1000 =20 g
