Answer:
Dissolve 226 g of KCl in enough water to make 1.5 L of solution
Explanation:
1. Calculate the moles of KCl needed
![n = \text{1.5 L} \times \dfrac{\text{2 mol}}{\text{1 L}}= \text{3.0 mol}](https://tex.z-dn.net/?f=n%20%3D%20%5Ctext%7B1.5%20L%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B2%20mol%7D%7D%7B%5Ctext%7B1%20L%7D%7D%3D%20%5Ctext%7B3.0%20mol%7D)
2. Calculate the mass of KCl
![m = \text{3.0 mol} \times \dfrac{\text{74.55 g}}{\text{1 mol}}= \text{224 g}](https://tex.z-dn.net/?f=m%20%3D%20%5Ctext%7B3.0%20mol%7D%20%5Ctimes%20%5Cdfrac%7B%5Ctext%7B74.55%20g%7D%7D%7B%5Ctext%7B1%20mol%7D%7D%3D%20%5Ctext%7B224%20g%7D)
3. Prepare the solution
- Measure out 224 g of KCl.
- Dissolve the KCl in a few hundred millilitres of distilled water.
- Add enough water to make 1.5 L of solution.
Mix thoroughly to get a uniform solution.
Answer:
During MITOSIS, the parent, diploid (2n), cell is divided to create two identical, diploid (2n), daughter cells. ... After cytokinesis, the ploidy of the daughter cells remains the same because each daughter cell contains 4 chromatids, as the parent cell did.
