Answer:
0.129 L = 129.0 mL.
Explanation:
- NaOH neutralizes acetic acid (CH₃COOH) according to the balanced reaction:
<em>NaOH + CH₃COOH → CH₃COONa + H₂O. </em>
- According to the balanced equation: 1.0 mole of NaOH will neutralize 1.0 mole of CH₃COOH.
<em>no. of moles of CH₃COOH = mass/molar mass </em>= (2.0 g)/(60 g/mol) = <em>0.033 mole. </em>
<em>
</em>
no. of moles = (0.258 mol/L)(V)
- At neutralization: no. of moles of NaOH = no. of moles of CH₃COOH
∴ (0.258 mol/L)(V) = 0.033 mole
<em>∴ The volume of NaOH</em> = (0.033 mole)/(0.258 mol/L) = <em>0.129 L = 129.0 mL.</em>
13 liters is the correct answer
13 liters is the final volume of the gas when the temperature and pressure remain constant.
v1/n1 = v2/n2
where,
v1 = initial volume = 8.5 liter
n1= initial mole of gas = 1.2 mole
n2= final mole of gas = 1.2+0.65= 1.85 mole
v2= final volume = ?
8.5 L/1.2 mol = v2/1.85 mol
7 L x 1.85 mol = v2/1.85 mol x 1.85 mol
13 L = v2
v2= 13 liter
<h3>What is a mole?</h3>
- A mole is an SI unit used to measure significant numbers of subatomic particles, such as atoms, molecules, or smaller particles.
- Any substance has an Avogadro number of molecules in a mole.
- The value of the Avogadro number is 6.02214076 × .
<h3>How much is a mole of gas?</h3>
22.4 L
At STP (Standard Temperature and Pressure = 0 °C, 1 atm), an ideal gas has a volume of 22.41 L/mol.
<h3>What makes something a mole?</h3>
- Chemists use the term "mole" because atoms, molecules, and other particles are all very small and require a large amount to even weigh them.
- A mole is a measurement of the number of particles present, not their mass.

|F| = 112 - 67 = 45 N
F = 45 N ( to the left)
The number of same atom needs to be equal at both sides of the equation. According to this rule, we can get the balanced equation: 2C6H14 + 19O2 -> 12CO2 + 14H2O.
