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:
Answer is (D) A chemical reaction did not take place.
What Jonathan created was a mixture.
I don't know what you are talking about but if you are asking about the difference between <span>electric discharge and electric current then;</span>
The electric current is the amount of electrons or charges passing through a conductor per units of time. 1 ampere = 1 coulombs / 1 second.
Electric discharge is the consequence of disrupting an isolator (for example, air), thus causing a sudden flow of electricity.
