  • Dime=2.26g
  • Nickel=4.97g

\\ \rm\Rrightarrow Avg\:Weight=\dfrac{Sum\:of\:Weights}{No\:of\:weights}

\\ \rm\Rrightarrow Avg\:weight=\dfrac{2.26+4.96}{2}

\\ \rm\Rrightarrow Avg\;weight=\dfrac{7.23}{2}

\\ \rm\Rrightarrow Avg\:Weight=3.6g

Start with 100.00 mL of 0.10 M acetic acid, CH3COOH. The solution has a pH of 2.87 at 25 oC. a) Calculate the Ka of acetic acid
jasenka [17]

Answer: a) The K_a of acetic acid at 25^0C is 1.82\times 10^{-5}

b) The percent dissociation for the solution is 4.27\times 10^{-3}

Explanation:

CH_3COOH\rightarrow CH_3COO^-H^+

 cM              0             0

c-c\alpha        c\alpha          c\alpha

So dissociation constant will be:

K_a=\frac{(c\alpha)^{2}}{c-c\alpha}

Give c= 0.10 M and \alpha = ?

Also pH=-log[H^+]

2.87=-log[H^+]  

[H^+]=1.35\times 10^{-3}M

[CH_3COO^-]=1.35\times 10^{-3}M

[CH_3COOH]=(0.10M-1.35\times 10^{-3}=0.09806M

Putting in the values we get:

K_a=\frac{(1.35\times 10^{-3})^2}{(0.09806)}

K_a=1.82\times 10^{-5}

b)  \alpha=\sqrt\frac{K_a}{c}

\alpha=\sqrt\frac{1.82\times 10^{-5}}{0.10}

\alpha=4.27\times 10^{-5}

\% \alpha=4.27\times 10^{-5}\times 100=4.27\times 10^{-3}

What is a the volume of a salt crystal measuring 3.22 x 10^-2 cm by 1.5 x 10^-4 cm by 4.30 x 10^-3 cm?
aleksandr82 [10.1K]
Dimension of the salt crystal is:

Length = 3.22 x 10^-2 cm

Breadth = 1.5 x 10^-4 cm

Height = 4.30 x 10^-3 cm

So it is cuboidal in shape.

Volume = L × B × H

V = 3.22 \times  {10}^{ - 2}  \times 1.5 \times  {10}^{ - 4}  \times 4.30 \times  {10}^{ - 3}  \\  \\ V = 3.22 \times 1.5 \times 4.30 \times  {10}^{ (- 2 - 3 - 4)}  \\  \\ V = 20.769\times  {10}^{ - 9} \\  \\ V = 2.0769 \times  {10}^{ - 8} \\  \\ V  \approx 2.1 \times  {10}^{ - 8} \:  {cm}^{3}  \\  \\  \boxed{ \red{ \bold{answer: a}}}
