Answer:
The answer to your question is: V1 = 27.8 ml of HCl 18 M
Explanation:
Data
HCl = [18M]
HCl Vol = ?
HCl = [ 2M]
HCl vol = 250 ml
Formula
V₁ C₁ = V₂ C₂
V₁ = V₂ C₂ / C₁
Process (substitution)
V₁ = (250)(2) / 18
V₁ = 500 / 18
V1 = 27.8 ml
To find moles in this sample, you would divide grams by molar mass of ethyl alcohol
(18.0g)/(46.07g/mol) = 0.391mol C2H6O
<u>Answer:</u> The boiling point of solution is 100.62°C
<u>Explanation:</u>
Elevation in boiling point is defined as the difference in the boiling point of solution and freezing point of pure solution.
The equation used to calculate elevation in boiling point follows:
To calculate the elevation in boiling point, we use the equation:
Or,
where,
Boiling point of pure water = 100°C
i = Vant hoff factor = 1 (For non-electrolytes)
= molal boiling point elevation constant = 0.512°C/m.g
= Given mass of solute = 23.6 g
= Molar mass of solute = 103.5 g/mol
= Mass of solvent (water) = 188 g
Putting values in above equation, we get:
Hence, the boiling point of solution is 100.62°C
So you can be safe and noting bad can happen to you
