Answer: True
Explanation: Specific Gravity of a body, also called its Relative Density, is the ratio of the density of that body to the density of a reference material (usually water).
With the Mathematics done right, it is evident that the specific gravity of a body would be equal to the ratio of mass/weight of the body to the mass/weight of an equal volume of water.
S.G = (Density of body)/(Density of water)
Density of Body = (mass/weight of body)/(volume of body)
Density of water = (mass/weight of water)/(volume of water)
If volume of Body = Volume of water, then,
S.G = (Mass/Weight of body)/(Mass/Weight of equal volume of water)

To determine the Ka of the acid, we can use the equation for the pH of weak acids which is expressed as:
pH = -0.5 log Ka
2.67 = -0.5 log Ka
Ka = 4.571x10^-6
Weak acids are acids that do not dissociate completely in solution. The solution would contain the cations, anions and the acid itself as a compound. Hope this helps.
