Will have to fill in the graph organizer with a story
Answer:
Explanation:
Given that,
The distance between the centers of the two oxygen atoms in an oxygen molecule is 
.
We need to convert this distance in inches.
We know that,
1 cm = 0.393 inches
We can solve it as follows :
So, the distance between the centers of the two oxygen atoms is 
.
Answer:
34.9 g/mol is the molar mass for this solute
Explanation:
Formula for boiling point elevation: ΔT = Kb . m . i
ΔT = Temperatures 's difference between pure solvent and solution → 0.899°C
Kb = Ebullioscopic constant → 0.511°C/m
m = molality (moles of solute/1kg of solvent)
i = 2 → The solute is a strong electrolyte that ionizes into 2 ions
For example: AB ⇒ A⁺ + B⁻
Let's replace → 0.899°C = 0.511 °C/m . m . 2
0.899°C / 0.511 m/°C . 2 = m → 0.879 molal
This moles corresponds to 1 kg of solvent. Let's determine the molar mass
Molar mass (g/mol) → 30.76 g / 0.879 mol = 34.9 g/mol
20.58 by using a calculator you can determine this, then round
