Answer:
2.03
Explanation:
Let's <u>assume we have 1 L of the solution</u>:
- There would be 2.07 ethylene glycol moles.
- The solution would weigh (1000 mL * 1.02 g/mL) = 1020 g.
With that information we can <u>calculate the molality</u>:
- molality = moles of solute / kg of solvent
- molality = 2.07 moles / (1020 ÷ 1000) = 2.03 m
Keep in mind that this is only an estimate, as we used the kg of the solution and not of the solvent.
3.456 x 10^2 is the answer you're looking for.
Answer:
They had a negative charge
Explanation:
Chemistry is concerned with:
1) Composition
The composition of matter helps determine how it will behave chemically and physically, and is studied in chemistry
2) Structure
The structure of a certain element or compound also governs how the substance behaves, making it another vital aspect of chemistry
3) Behavior
The behavior of substances is studied in order to have explanations presented for it, expanding our understanding.
