I’m pretty sure it’s gravity man
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.
М(СО₂)=165 г
н(СО₂)=м(углекислого газа)/М(СО₂)
Н=Nₐ*м(углекислого газа)/М(СО₂)
Н=6.022*1023 * 165/44.01=2.258*10²⁴
