The number of molecules in 1 mol of oxygen compare with the number of molecules in 1 mol of nitrogen is that e<span>ach sample has the same number of molecules. The answer is number 3</span>
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
Answer:
10 moles
Explanation:
of moles = given mass /atomic mass = 280 g /28 g = 10 moles of Si atoms in 280g sample.
