Answer:
The molecular weight is 77.7 kg/mol
Explanation:
The molecular mass of hemoglobin is equal to:
Where
R = molar gas constant = 8.315 J/K mol
p = density = 0.998 g/mL
V = specific volume = 0.755 mL/g
s = sedimentation rate = ?
D = diffusion rate = 7x10⁻¹¹m²/s
T = temperature = 303 K
The sedimentation rate is equal to:
Where
w = angular velocity = 39300 rpm = 246929.18 rad/min
xb,30 = boundary midpoint distance at 30 min = 4.525 + 0.074 cm
t = time = 30 min
xb,0 = boundary midpoint distante at 0 min = 4.525 cm
The molecular weight is:
H2-element
HCl-compound
Na-element
Al2O3-compound
H2O-compound
Answer:
This is hard for me also but I am trying to find out answer
Explanation:
Please mark me as brainlist.
Is there answers to go along with this? it should be Dark/Brown hair
Well I'm sure many a time you've seen on some science experiment someone wrap a copper wire around a nail well thats generally the idea for electromagnets you get a solid piece of iron which is the only metal that is magnetic and you wrap a copper wire around it and the idea is to make two opposing magnetic poles by aligning the molecules with a electrical charge (a battery) so now with all three pieces assembles you have a copper wire attached to two sides of a battery and wrapped around a nail
