What measurements are used to calculate the density of a given object?

professor190 [17]

Answer:

Density = $\frac{Mass}{Volume}$

Explanation:

Density equals mass divided by volume.

Density often has units of grams per cubic centimeter (g/cm3). Remember, grams is a mass and cubic centimeters is a volume (the same volume as 1 milliliter).

Hippuric acid (HC9H8NO3)(HC9H8NO3), found in horse urine, has pKa=3.62pKa=3.62. Part A Calculate the pHpH in 0.140 MM hippuric a

Oxana [17]

Answer:

The pH in 0.140 M hippuric acid solution is 2.2.

Explanation :

Dissociation constant of the acid = $K_a$

$pK_a=-\log[K_a]$

$3.62=-\log[K_a]$

$K_a=2.399\times 10^{-4}$

Concentration of hippuric acid = c = 0.140 M

$HC_9H_8NO_3\rightleftharpoons C_9H_8NO_{3}^-+H^+$

Initially

c 0 0

At equilibrium

(c-x) x x

Concentration of acid = c $[HC_9H_8NO_3]=0.140 M$

Dissociation constant of an acid is given by:

$K_a=\frac{[C_9H_8NO_{3}^-][H^+]}{[HC_9H_8NO_{3}]}$

$K_a=\frac{x\times x}{(c -x)}$

$2.399\times 10^{-4}=\frac{x\times x}{(0.140 -x)}$

Solving for x:

x = 0.005677 M

$[H^+]=x = 0.005677 M$

The pH of the solution :

$pH=-\log[H^+]$

$pH=-\log[0.005677 M]=2.246\approx 2.2$

The pH in 0.140 M hippuric acid solution is 2.2.

If i were to put cesium in water and francium in a tub of water which one would explode first?

hoa [83]

Well according to me Cesium releases enough energy that even a small piece blows up in water. Francium is below cesium on the table and would react more readily and violently.
