The density of a monobasic strong acid (Molar mass $242 \,g$ mol) is $121 \,kg \,L$ The volume of its solution required for the complete neutralization of $25 \,mL$ of $024\, M\, NaOH$ is ___$\times 10^{-2} mL$ (Nearest integer)
1. Calculate millimoles of NaOH: \[ \text{Millimoles of NaOH} = 0.24 \times 25 = 6 \, \text{mmol}. \] 2. Since the acid is monobasic, millimoles of acid required = millimoles of NaOH = 6 mmol. 3. Mass of acid required: \[ \text{Mass of acid} = 6 \times 24.2 = 145.2 \, \text{mg}. \] 4. Volume of acid solution: Using \(\text{Volume} = \frac{\text{mass}}{\text{density}}\), \[ V = \frac{145.2}{1.21 \times 10^3} = 0.12 \, \text{mL}. \] 5. Convert to \(10^{-3}\): \[ V = 12 \times 10^{-3} \, \text{mL}. \] Thus, the volume required is 12\(\times\)\(10^{-3} mL\). Neutralization of a monobasic acid requires equal millimoles of acid and base. Use the density of the acid solution to calculate the required volume.
Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
