Question

Heme molecules are responsible for the red pigmentation of blood cells. Differing chemically isolated molecular heme compounds are named as "Heme X" (where "X" is a variable denoting the actual molecular fragments which are represented by the labels R$_3$, R$_8$, and R$_{18}$). Suppose one molecule of Heme X contains 5 oxygen atoms, and Heme X is 12.65% oxygen by weight. Using only this information and the atomic mass of oxygen, determine the molecular mass of Heme X. 1.919x10^23 amu Submit Answer Incorrect. Tries 4/5 Previous Tries The Heme X molecule contains one iron atom. What mass of iron is found in 3.51 g of Heme X compound?

Step 1

Since Heme X contains 5 oxygen atoms and the atomic mass of oxygen is approximately 16 amu, the total mass of oxygen is: 5 atoms × 16 amu/atom = 80 amu. Show more…

What mass of iron is found in 3.51g of Heme x compound? Heme molecules are responsible for the red pigmentation of blood cells. Differing chemically isolated molecular heme compounds are named as Heme X (where x" is a variable denoting the actual molecular fragments which are represented by the labels R3, Rg, and R1s). Suppose one molecule of Heme X contains 5 oxygen atoms, and Heme X is 12.65 % oxygen by weight.
