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.
The number of electrons. The valence (outer) shell is particularly important.
The answer to your question is false.
I think it's fertilisation (^^)
Answer:
Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.
