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:
the number of possible configurations of the locations and energies of the atoms or molecules that comprise a system
Explanation:
Ludwig Boltzmann suggested that the concept of entropy may be calculated from close examination of the positions and energies of molecules. He developed this idea into an equation, known as the Boltzmann equation, which relates entropy to the number of microstates (W):
S = k ln W
where k is the Boltzmann constant (1.38 x 10-23 J/K), and W is the number of microstates.
Microstates was simply defined as the number of different possible arrangements of molecular position and kinetic energy at a particular thermodynamic state. Hence, any process that gives an increase in the number of microstates therefore increases the entropy.
Answer:
9.96 × 10⁸
Explanation:
Step 1: Calculate the diameter of 1 aluminum atom
The diameter of a sphere is 2 times the radius.
d = 2 × 140 pm = 280 pm
Step 2: Convert "d" to m
We will use the conversion factor 1 m = 10¹² pm.
280 pm × 1 m/10¹² pm = 2.80 × 10⁻¹⁰ m
Step 3: Convert the total length (L) to m
We will use the conversion factor 1 m = 100 cm.
27.9 cm × 1 m/100 cm = 0.279 m
Step 4: Calculate the number of atoms of aluminum required
We will use the following expression.
L/d = 0.279 m/2.80 × 10⁻¹⁰ m = 9.96 × 10⁸
