To determine the mass of gasoline in the the tank, we need data on the density of gasoline. We multiply this value to the capacity of the gasoline tank. We do as follows:
Mass = 13 gallons (0.0038 m^3 / 1 gallons) ( 732.22 kg/m^3 ) = 36.17 kg or 361771.67 g
36.17 kg ( 2.2 lb / 1 kg ) = 79.58 lb
Answer : The hydroxide ion concentration of a solution is, 
Explanation :
As we know that:
pH : It is defined as the negative logarithm of hydrogen ion concentration.
Mathematically,
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
Similarly,
pOH : It is defined as the negative logarithm of hydroxide ion concentration.
Mathematically,
![pOH=-\log [OH^-]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%20%5BOH%5E-%5D)
Given:
pOH = 6.42
![6.42=-\log [OH^-]](https://tex.z-dn.net/?f=6.42%3D-%5Clog%20%5BOH%5E-%5D)
![[OH^-]=3.8\times 10^{-7}M](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D3.8%5Ctimes%2010%5E%7B-7%7DM)
Therefore, the hydroxide ion concentration of a solution is,
Answer:Types of Ions: ... Ionic Compounds Containing a Metal and a Polyatomic Ion 3. ... Molecular Masses from Chemical Formulas ... A cation is a positively charged ion; An anion is a negatively charged ion. ... for these ions are derived by naming the metal first, followed in parentheses by the charge written in Roman numerals.
Answer:
X linked recessive
Explanation:
Being an X linked recessive a disorder is more prevalent in males as compared to females because a single X chromosome in male is able to expresses the trait.
In case of female untill unless there are two sets of X linked recessive allele, there will be no disorder. Infact most of the women are carrier only
The final temperature of the lead-water system will be lower than the final temperature of the copper-water system.
