Answer:
1 It gives the cell its structure
2 It regulates the materials that enter and leaves the cell
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.

Step 2: Calculate the moles of the solute
The molality is equal to the moles of solute divided by the kilograms of solvent. Then,

B. curiosity and i know because i had the exact question
N = m/M
Where,
n = number of moles
m = mass of substance
M = molar mass of substance
0.8286 = m / 30.067
Multiply both sides by 30.067
m = 24.9135162g
