You are given the molarity of the solution which is 1x10-5 M. Since molarity is moles of solute over liters solution. You could determines the moles.
M=m/V
1x10-5 = m/(2 L)
m = 2x10-5 moles ligand A
We could determine the mass of ligand A by using the molar weight:
2x10-5 mol * 250 g/mol = 0.005 grams of ligand A
I hope I was able to answer your question. Have a good day.
The elastic artery absorb most of the shock when the heart ejects blood. The expansion stores energy; the recoil disperses this energy by moving blood further through the circulation.
since a cell has 6 sides :
L= length, W= width
surface area = ( L x W ) X 6
= (2 X2 ) X 6
= 4 X 6
= 24 cm²
The Hubble Constant is used as an indication of the universe expansion. When astronomers find the distances between stars, they use methods of parallax or the stars brightness.

Answer:
The sound waves then travel toward a flexible, oval membrane at the end of the ear canal called the eardrum, or tympanic membrane.
Explanation:
The auricle (pinna) is the visible portion of the outer ear. It collects sound waves and channels them into the ear canal (external auditory meatus), where the sound is amplified.
