hemoglobin, the oxygen-carrying protein in red blood cells, has four iron atoms per molecule and contains .340 percent iron by mass. calculate the molar mass of hemoglobin!

thanks! :)

(4*Fe/molar mass)*100 = 0.340

Solve for molar mass.

To calculate the molar mass of hemoglobin, we need to know the molecular formula and the molar mass of each element present in the molecule.

From the information given, we understand that hemoglobin contains four iron atoms per molecule and that iron constitutes 0.340% of the mass of hemoglobin.

Let's assume the molecular formula of hemoglobin is Hb.

To calculate the molar mass of hemoglobin, we need to find the molar mass of iron and multiply it by the number of iron atoms in one molecule of hemoglobin. Then we divide the result by the percentage of iron by mass present in hemoglobin.

The atomic mass of iron (Fe) is 55.845 g/mol.

First, we calculate the molar mass of iron (Fe):
Molar mass of iron = 55.845 g/mol

Next, we calculate the molar mass of hemoglobin:
Molar mass of hemoglobin = (Molar mass of iron) × (Number of iron atoms per molecule of hemoglobin) / (Percentage of iron by mass in hemoglobin)

Molar mass of hemoglobin = (55.845 g/mol) × 4 / (0.340/100)

Calculating this equation, we have:
Molar mass of hemoglobin ≈ 26117.647 g/mol

Therefore, the molar mass of hemoglobin is approximately 26117.647 g/mol.

Please note that this is an approximation, and the actual molar mass of hemoglobin may differ slightly due to the presence of other elements and their masses in the molecule.

To calculate the molar mass of hemoglobin, we need to use the information provided about its iron content.

Step 1: Calculate the mass of iron in one molecule of hemoglobin.
Since hemoglobin contains four iron atoms per molecule and the iron content is 0.340% by mass, we can calculate the mass of iron as follows:
Mass of iron = 0.340% x molar mass of hemoglobin
We can rearrange this equation to find the molar mass of hemoglobin:
Molar mass of hemoglobin = Mass of iron in one molecule of hemoglobin / (0.340% x 4)

Step 2: Convert the mass of iron to grams.
To convert the percentage to a decimal, divide by 100. Therefore, the iron content is 0.340 / 100 = 0.00340.
Next, we need to find the mass of iron in one molecule of hemoglobin. To do this, we multiply the molar mass of iron by the number of iron atoms in hemoglobin.
Mass of iron = 55.845 g/mol (molar mass of iron) x 4 (number of iron atoms per molecule of hemoglobin)

Step 3: Calculate the molar mass of hemoglobin.
Now, we'll substitute the values from step 2 into the equation:
Molar mass of hemoglobin = (55.845 g/mol x 4) / (0.00340 x 4)

By evaluating this expression, we find the molar mass of hemoglobin.

Note: Make sure to use the correct values and units in the calculations.
