To neutralize acids, a weak base is used. Bases have a bitter or astringent taste and a pH greater than 7. Common bases are sodium hydroxide, potassium hydroxide and ammonium hydroxide. Bases are neutralized by using a weak acid.

Suppose you are measuring the mass of a sample using a balance that employs a standard mass of density dw = 8.0 g/ml. what is th

sleet_krkn [62]

The buoyant force formula is:

$B = \rho Vg$

where $B$ is Buoyant force, $\rho$ is density, $V$ is displaced body volume and $g$ is $9.806 ms^{-2}$ (standard gravity).

The standard mass density of the sample, $\rho _{1}$ = $8 g/ml$

If the dansity of the sample, $\rho _{2}$ $< 8 g/ml$

The buoyancy correction is determined by the ratio:

$\frac{B_{1}}{B_{2}} = \frac{\rho_{1} Vg}{\rho_{2} Vg}$

$\frac{B_{1}}{B_{2}} = \frac{\rho_{1}}{\rho_{2}}$

$\frac{B_{1}}{B_{2}} = \frac{\rho_{1}}{\rho_{2}}>1$

Hence, the the buoyancy correction is positive.
