haemoglobin contains 0.25% iron by weight. The molecular weight of haemoglobin is 896000. Calculate the number o iron atom per molecule of haemoglobin.
calculate the amount of Ni needed in the mond's process given below Ni + 4CO --- Ni(CO)4 if CO used in this process is obtained through a process, in which 6g of carbon is mixed with 44 g CO2 is
the number of electrons present in an Azide ion (N3-)?
calculate the numbers of atom of C and O in 72.5g isopropanol C3H7OH (MOLAR MASS 60)
40ml of a mixture of c2h2 and co is mixed with 100ml of o2 gas and the mixture is exploded. the residual gases occupied 104ml and when these are passed through KOH solution, the volume becomes 48ml. all the volume are at same temperature and pressure. determine the composition of original mixture
