<span>An orbital can only have two copies of its electron. Primarily there is only one orbital however it can be filled twice which therefore suggests in total there would be 2 copies. As an example, 3 orbitals would be able to possess 6 electronic copies</span>
Answer:
pretty sure they're called groups
Answer:
1.6 °C.kg/mol
Explanation:
Step 1: Calculate the molality of urea
We will use the following expression.
m = mass(urea) / molar mass(urea) × kg solvent
m = 24.6 g / 60.06 g/mol × 0.650 kg
m = 0.630 mol/kg
Step 2: Calculate the boiling point elevation of X
The boiling point elevation is a colligative property that can be calculated using the following expression.
ΔTb = 124.3 °C - 123.3 °C = 1.0 °C
Step 3: Calculate the boiling point elevation constant
We will use the following expression.
ΔTb = Kb × m
Kb = ΔTb/m
Kb = 1.0 °C/(0.630 mol/kg) = 1.6 °C.kg/mol
Solubility is a chemical property referring to the ability for a given substance, the solute, (gas) to dissolve in a solvent (liquid). It is measured in terms of the maximum amount of solute dissolved in a solvent at equilibrium. The resulting solution is called a saturated solution.
