The amount of CD is 35 g, and the amount of AC is 40 g.
The taste and odors in fruits are often the result of the ester components of the fruits. Esters are organic compounds produced from the reaction of alcohol and carboxylic acid. For example, bananas have esters called isomyl acetate, citrus fruits have octyl acetates familiar in oranges, lemon, tangerine, grapefruits, etc., and many others.
Answer:
0.0428 M
Explanation:
Because we're asked to calculate the molarity of nickel(II) cation, we need to <u>determine all sources for that species</u>, in this case, all Ni⁺² comes from the nickel(II) bromide solid (NiBr₂).
We use the molecular weight of NiBr₂ to calculate the moles of Ni:
1.87 g NiBr₂ ÷ 218.49g/mol * (1molNi⁺²/1molNiBr₂) = 8.55x10⁻³ mol Ni⁺²
Then we <u>divide the moles by the volume in order to calculate the concentration</u>:
8.55x10⁻³ mol Ni⁺² / 0.200 L = 0.0428 M
