When 200 mL of 0.2 M acetic acid is shaken with 0.6 g of wood charcoal, the final concentration of acetic after adsorption is 0.1 M. The mass of acetic acid adsorbed per garm of carbon is g.

Question

When 200 mL of 0.2 M acetic acid is shaken with 0.6 g of wood charcoal, the final concentration of acetic after adsorption is 0.1 M. The mass of acetic acid adsorbed per garm of carbon is g. (A)  (B)  (C)  (D)

Tardigrade Admin · Accepted Answer

weight of wood charcoal =0.6 g Mass of acetic acid adsorbed =( M 1 V 1- M 2 V 2/1000) × 60 =(0.2 × 200-0.1 × 200/1000) × 60 =1.2 g Mass of acetic acid adsorbed per gram of carbon =(1.2/0.6)=2

Q. When $200 m L$ of $0.2 M$ acetic acid is shaken with $0.6 g$ of wood charcoal, the final concentration of acetic after adsorption is $0.1 M$ . The mass of acetic acid adsorbed per garm of carbon is _____ $g$ .

weight of wood charcoal $= 0.6 g$
Mass of acetic acid adsorbed $= \frac{M _{1} V _{1} - M _{2} V _{2}}{1000} \times 60$
$= \frac{0.2 \times 200 - 0.1 \times 200}{1000} \times 60$
$= 1.2 g$
Mass of acetic acid adsorbed per gram of
carbon $= \frac{1.2}{0.6} = 2$

Q. When 200mL of 0.2M acetic acid is shaken with 0.6g of wood charcoal, the final concentration of acetic after adsorption is 0.1M. The mass of acetic acid adsorbed per garm of carbon is _____ g.

weight of wood charcoal =0.6g Mass of acetic acid adsorbed =1000M1​V1​−M2​V2​​×60 =10000.2×200−0.1×200​×60 =1.2g Mass of acetic acid adsorbed per gram of carbon =0.61.2​=2

Q. When $200 m L$ of $0.2 M$ acetic acid is shaken with $0.6 g$ of wood charcoal, the final concentration of acetic after adsorption is $0.1 M$ . The mass of acetic acid adsorbed per garm of carbon is _____ $g$ .

weight of wood charcoal $= 0.6 g$
Mass of acetic acid adsorbed $= \frac{M _{1} V _{1} - M _{2} V _{2}}{1000} \times 60$
$= \frac{0.2 \times 200 - 0.1 \times 200}{1000} \times 60$
$= 1.2 g$
Mass of acetic acid adsorbed per gram of
carbon $= \frac{1.2}{0.6} = 2$
