The role of rhinos in the food chain is... <span>White rhinos are grass-grazing animals, while black rhinos are low browsers. They fill similar roles in their ecosystems to other grazers and browsers. Their size means they eat a LOT, and also means that generally only their offspring are preyed on. So, recycling and trampling high-carbon foliage into fertilizer is their main function.
hope this helped</span>
Answer:
0.18 mol
Explanation:
Given data
- Mass of carbon tetrachloride (solvent): 750 g
- Molality of the solution: 0.24 m
- Moles of iodine (solute): ?
Step 1: Convert the mass of the solvent to kilograms
We will use the relationship 1 kg = 1,000 g.
![750g \times \frac{1kg}{1,000g} =0.750kg](https://tex.z-dn.net/?f=750g%20%5Ctimes%20%5Cfrac%7B1kg%7D%7B1%2C000g%7D%20%3D0.750kg)
Step 2: Calculate the moles of the solute
The molality is equal to the moles of solute divided by the kilograms of solvent. Then,
![m = \frac{moles\ of\ solute }{kilograms\ of\ solvent} \\moles\ of\ solute = m \times kilograms\ of\ solvent = \frac{0.24mol}{kg} \times 0.750kg = 0.18 mol](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7Bmoles%5C%20of%5C%20solute%20%7D%7Bkilograms%5C%20of%5C%20solvent%7D%20%5C%5Cmoles%5C%20of%5C%20solute%20%3D%20m%20%5Ctimes%20kilograms%5C%20of%5C%20solvent%20%3D%20%5Cfrac%7B0.24mol%7D%7Bkg%7D%20%20%5Ctimes%200.750kg%20%3D%200.18%20mol)
