ou discover that the complex decomposes in water. When 0.1000 g of the complex is dissolved in water with excess NaHg(SCN)4, all of the Co(II) is precipitated as CoHg(SCN)4 (s). After the precipitate is washed and dried, its mass is found to be 0.1102 g. How many grams of cobalt are contained in the original 0.1000 grams of the complex

6.28x10⁻³ g

Explanation:

First we convert 0.1102 grams of CoHg(SCN)₄ into moles, using its molar mass:

There is 1 Co mol per CoHg(SCN)₄ mol, meaning there's also 2.24x10⁻⁴ moles of Co.

We now convert 2.24x10⁻⁴ moles of Co into grams, using its molar mass:

neutrons are in the middle of the atom and the electrons, which are much smaller.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
