Determined on basis of baseline platelet count, desired platelet count, and estimated blood volume. For 70 kg patient, 4 x 10 11 platelets (about 4 units WB platelets or 1 apheresis platelet), platelet increment of approximately 30,000/ul is expected in the absence of alloimmunization or excessive consumption.
Zinc has 30 protons. The number of electrons varies, depending on ionization state, and is 30 for the neutral state. The number of neutrons varies, with 30 different isotopes â¦known to exist. 5 are stable, having 34, 36, 37, 38, and 40 neutrons.
The number of protons in the nucleus is equal to atomic number, Z while the number of neutrons in the nucleus is sometimes called neutron number, N. Mass number gives the approximate atomic mass of the element. For example, mass number of magnesium is 24 as it contains 12 protons and 12 neutrons in its nucleus.
