Answer:
1.04 L
Explanation:
Charles law states that for a fixed mass of gas, volume of gas is directly proportional to the absolute temperature at constant pressure.
where V1 is the volume and T1 is absolute temperature at first instance
and V2 is volume and T2 is absolute temperature at the second instance
Absolute temperature is temperature in the kelvin scale
T1 - 25 °C + 273 = 298 K
T2 - -15 °C + 273 = 258 K
substituting the values in the equation
V2 = 1.04 L
when the temperature is -15 °C the volume is 1.04 L
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>

I don’t quite understand the question but i believe your answer would be using electrostatic precipitators
