Density (d) is the ratio of the substance mass (m) to its volume (v).
d = m / v
Rearranging the equation gives us the equation for volume which is,
v = m / d
Substituting the values,
v = 3 g / (8.9 g/cm³)
v = 0.34 cm³
The substance occupies approximately 0.34 cm³.
Here, the buffer is NH₄Cl + NH₃
The strong base is added to the buffer solution, then the salt reacts with base to form weak base and water, which does not alter the pH
NH₄Cl + CsOH → NH₃ + CsCl + H₂O
NH₄⁺ + OH⁻ → NH₃ + H₂O
When we add a strong acid to the buffer solution, the base NH₃ reacts with acid and forms salt, which does not alter the pH
NH₃ + H⁺ → NH₄⁺
Answer: 20 + 1 + 3.8 + 2.4 +27 = 54.2
Explanation: 20 gallons plus 1 gallon plus 3.8 plus 2.4 plus 27 equals to a total number of 54.2 gallons for the propane.
KH2O? Maybe that will work?
