You would need instructions. Do it with science materials.
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
Acacia ant and acacias animals are an example of coevolution
Coevolution is the reciprocal evolutionary change in a set of interacting population over time resulting from the interaction between those population and an example of coevolution that is not characteristics of an arm race but one which provides a mutual benefit to both a plant species and insect is that of the acacia ant and acacia plant and many cases of coevolution can be found between plants and insects
