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.
Copper should not be disposed of in landfill sites
because the dust and waste gases of copper is very harmful to the environment. It
can leached into the ground possibly affecting the underground water.
Answer:
Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (commonly called iso-octane) is used as one of the standard values in the octane rating scale.
Chemical formula: C₈H₁₈
Molar mass: 114.232 g·mol−1
Melting point: −57.1 to −56.6 °C; −70.9 to −69.8 °F; 216.0 to 216.6 K
Solubility in water: 0.007 mg dm−3 (at 20 °C)
