Question

A certain protein was found to contain 0.513% iron by mass. Determine the minimum molecular mass of the protein?

Answer 1

To determine the minimum molecular mass of the protein, we need to calculate using the percentage of iron in the protein and the molar mass of iron.

Step-by-step explanation:

To determine the minimum molecular mass of the protein, we need to know the percentage of iron in the protein and the molar mass of iron. Given that the protein contains 0.513% iron by mass, we can calculate the minimum molecular mass as follows:

1. Find the molar mass of iron, which is 55.8 g/mol.
2. Set up a proportion using the percentage of iron and the molar mass of the protein:

x / 100% = 0.513% / 55.8 g/mol

Solve for x, which represents the minimum molecular mass of the protein:

x = (0.513% / 55.8 g/mol) * 100%

Calculate x to find the minimum molecular mass of the protein.
