How many oxygen molecules are in 25 g o2
WebVerified by Toppr Molecular weight of oxygen is 32. Thus the number of moles present in 16 g of O 2 will be 0.5 Number of molecules present will be 0.5N A Number of gram atoms will be 0.5×2N A=N A ( Since one molecule of oxygen contains 2 atoms of oxygen) 1 mol of a gas occupies 22.4l at STP, thus given sample will occupy 11.2l at STP. Web15 mei 2012 · Of an adult's haemoglobin, 2.2–3.5% is HbA 2, composed of two α- and two δ-chains. This form of haemoglobin is poor at oxygen carriage. Fetal haemoglobin (HbF) comprises two α-chains and two γ-chains. At birth, 50–95% of a baby's haemoglobin is HbF, but these levels decline after 6 months as more HbA is produced.
