A sample of hydrolysed potato starch is found to contain 0.086% phosphorus. If each molecule is assumed to contain one atom of phosphorus, the molecular mass of hydrolysed potato starch is (at. Mass of phosphorus = 31 u).

A sample of potato starch was ground in a ball mill to give a starchlike molecule of lower molecular weight. The product analysed 0.086% phosphorus. If each molecule is assumed to contain one atom of phosphorus, what is the molecular weight of the material?

Calculate the molar mass of Phosphorus molecule , P_(4) (Atomic mass of phosphorus = 31)

Haemoglobin contains 0.25% iron by weight. If one molecule of haemoglobin contains 4 atoms of iron, find the molecular mass of haemoglobin
