Answer;
= 64561.95 g/mole
Explanation;
mass of Fe in 100g = .346g
= .346 / 55.8452 moles
= 0.0061957 moles
These represent 4 moles of Fe in the molecule so moles of hemaglobin
= 0.0061957/4
= 0.0015489 moles
these are in 100 g so mass of 1 mole = 100 / 0.0015489
= 64561.95 g / mole
molar mass of hemoglobin = 64561.95 g/mole
An acid has several definitions one would be that it is a proton donor and an electron donor. Also, it said to produce an H+ ion when in solution. For nitric acid in solution, it dissociates into ions which are NO- ions and H+ ions. So, it must be an acid. It has a dissociation reaction:
HNO3 = H+ + NO3-
Answer:
Most of the food energy that enters a trophic level is "lost" as heat when it is used by organisms to power the normal activities of life. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy.
Explanation:
Answer:
a. Sb =0.280048 g , b. Ba=4.875215 g , c. Xe=5763.631 g , d. W=238.992 g
Explanation:
number of moles = 
(a) For Sb, molar mass =121.76g/mol
number of moles =2.3*
mol
<em>mass= number of moles * molar mass</em>
mass =2.3* *121.76
mass =0.280048 g
(b) for Ba, molar mass=137.33 g/mol
number of moles =0.0355 mol
mass = 0.0355 *137.33
mas = 4.875215 g
(c) for Xe, molar mass = 131.29 g/mol
number of moles =43.9 mol
mass =43.9 *131.29
mass =5763.631 g
(d) for W, molar mass = 183.84 g/mol
number of moles = 1.3mol
mass = 1.3 *183.84
mass = 238.992 g
