A scientist isolates a water-soluble compound from spider venom. The substance has nitrogen, carbon, hydrogen, and oxygen in its chemical structure. Based on this information, the compound is probably a .a. triglyceride
b. protein
c. polysaccharide
d. mineral salt.

b. protein

Explanation:

Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.

Triglycerides are made of a glycerol molecule esterified by three fatty acids.

Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.

The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

the increase of protons   hope this
