Answer:
27.06 mL.
Explanation:
- Firstly, we need to calculate the molarity of acrylic acid.
Molarity is the no. of moles of solute dissolved in a 1.0 L of the solution.
M = (no. of moles of acrylic acid)/(V of the solution (L))
M = (mass/molar mass)acrylic acid / (V of the solution (L))
mass of acrylic acid = 0.0975 g, molar mass of acrylic acid = 72.06 g/mol, V of the solution = 250 mL = 0.25 L.
∴ M = (0.0975 g/72.06 g/mol)/(0.25 L) = 0.0054 M.
- For the acid-base neutralization, we have the role:
The no. of millimoles of acid is equal to that of the base at the neutralization.
<em>∴ (XMV) NaOH = (XMV) acrylic acid.</em>
X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),
M is the molarity.
V is the volume.
X = 1, M = 0.05 M, V = ??? mL.
X = 1, M = 0.0054 M, V = 250.0 mL.
∴ V of NaOH = (XMV) acrylic acid/(XM) NaOH = (1)(0.0054 M)(250.0 mL)/(1)(0.05 M) = 27.06 mL.
Partial a because the liquid flow ate in the air
Your question, I guess, How do vapour and gases differ...
Answer:
1.) Vapour is the changed state of any liquid either due to boiling or evaporation
2.) Vapour are more energetic as they have absorbed the latent heat of vaporization whereas Gases are low in energy because they are already in gaseous form at room temperature.
3.) Vapour have boiling points above room temperature while gases have their boiling point below room temperature.
