Explanation:
Answer:
0.960 m
Explanation:
Given data
- Mass of the solute: 27.9 g
- Molar mass of the solute: 233.2 g/mol
- Mass of the solvent: 125.0 g = 0.1250 kg
First, we will calculate the moles of solute.
27.9 g × (1 mol/233.2 g) = 0.120 mol
The molality of the compound is:
m = moles of solute / kilograms of solvent
m = 0.120 mol / 0.1250 kg
m = 0.960 m
Tin has a molecular weight of 118.7 That is the mass in grams of one mole.

In the following compound of sucrose the atoms are as follows:
Carbon - 12 atoms
Hydrogen - 22 atoms
Oxygen - 11 atoms.
Answer:
12.5g
Explanation:
1. Percentage of solution = 5.
2. Mass of solution = 250g.
3. = Mass of solute / 250 x 100.
4. = 5 x 250 / 100.
5. = 12.5g.
