Soluble means that something will "dissolve" in a substance (typically water). This means that the substance is polar (like water)
insoluble is the opposite of soluble. It means that a substance will not dissolve in water. This means this is non-polar

You didn't post the whole question. However the answer would be : Mg, according to former questions in this website.
Hope this helps !

Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. ... In the central nervous system, axons are myelinated by oligodendrocytes, thus lack neurilemma.
Answer:
The mass of 3, 10 moles of MgCl2 is 295, 43 grams.
Explanation:
We calculate the weight of 1 mol of MgCl2:
Weight 1mol of MgCl2= weight Mg + (weight Cl)x 2=
24, 3 grams + 2 x 35, 5 grams = 95, 3 grams/mol MgCl2
1 mol MgCl2 ---------------95, 3 grams
3,1 mol MgCl2---------------x=(3,1 mol MgCl2x95,3 grams)/1 mol MgCl2
x=295, 43 grams
