Hemoglobin is the protein that transports oxygen in mammals. Different species of mammals have slightly different forms of hemog

lobin. One form of hemoglobin is 0.324% Fe by mass, and each hemoglobin molecule contains four iron atoms. Calculate the molar mass of this form of hemoglobin. Make sure to include units of g/mol. Enter your answer in Scientific notation with three significant figures. The Scientific notation for 2 x 10-4 would be written as 2E-4.

Answer:

The correct answer is - 6.8950.61 gm per mole

Explanation:

Given:

One form of hemoglobin is 0.324% Fe by mass

1 hemoglobin = 4 Fe

Solution:

Molar Mass of iron = 55.85

mass of 4 iron atom = 55.85 * 4 = 223.4 gms

0.324 % correspond to 223.4 gms

100 % correspond to = 223.4 *100/0.324

= 68950.61 gm

MM of haemoglobin = 68950.61 gms = 6.8 E4 gms

  How does the way animal cells use their vacuoles compare to the way plant cells use theirs?
ratelena [41]
The major difference is that plants use vacuoles to store excess amounts of water, while animal cells do not. A plant standing up straight compared to a plant wilting over is a result of water capacity in the vacuoles
