The density of lead (Pb) is 11.34 g/cm3. If I have 2.6 cm3, what mass of lead do I have?
1 answer:
Answer:
The answer is
<h2>29.48 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of lead = 2.6 cm³
density of lead = 11.34 g/cm³
The mass of lead is
mass = 11.34 × 2.6 = 29.484
We have the final answer as
<h3> 29.48 g</h3>

Answer:
The answer is "3".
Explanation:
acetic acid Dissociation:
Dissociation constant of the Ka:
![Ka = \frac{[CH3COO^{-}] [H^{+}]}{[CH_3COOH]}\\\\](https://tex.z-dn.net/?f=Ka%20%3D%20%5Cfrac%7B%5BCH3COO%5E%7B-%7D%5D%20%5BH%5E%7B%2B%7D%5D%7D%7B%5BCH_3COOH%5D%7D%5C%5C%5C%5C)
using the ICE table:
x is negligible compared to Ka.
![1.8\times 10^{-5} = \frac{x^2}{0.10}\\\\x^2 = 1.8 \times 10^{-6}\\\\x = 1.34 \times 10^{-3}\\\\pH = -\log [H^{+}]](https://tex.z-dn.net/?f=1.8%5Ctimes%2010%5E%7B-5%7D%20%3D%20%5Cfrac%7Bx%5E2%7D%7B0.10%7D%5C%5C%5C%5Cx%5E2%20%3D%201.8%20%5Ctimes%2010%5E%7B-6%7D%5C%5C%5C%5Cx%20%3D%201.34%20%5Ctimes%2010%5E%7B-3%7D%5C%5C%5C%5CpH%20%3D%20-%5Clog%20%5BH%5E%7B%2B%7D%5D)
From the ICE table, ![[H^{+}] = x = 1.34 \times 10^{-3}](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D%20%3D%20x%20%3D%201.34%20%5Ctimes%2010%5E%7B-3%7D)
