Answer:

0.054 M

Explanation:

1 mol NaHSO4 -> 120 g

                   x    ->13 g

x= 0.108 mol NaHSO4

M= mol solute/ L solution

M= 0.108 mol NaHSO4/ 2.00L

M= 0.054 M

Briefly explain why adding salt to icy roads helps melt the ice and prevent it from freezing again.
g100num [7]

Answer:

See explanation below

Explanation:

The melting point (the temperature that it changes from solid to liquid) of a pure substance depends on its mass, the forces between its molecules, and the pressure of the system.

The melting point, or the freezing point, of a mixture, is a temperature between the melting point of its components. Salt has a huge negative melting point, so when it is added to the water, the melting point decreases from 0ºC to -21ºC approximately.

So, the water will only freeze again if the temperature becomes below -21ºC which is very difficult to happen.

Calculate the ph of a 0.25M solution of monochloroacetic acid at 25 c
Phoenix [80]
<h3>Answer: <em>pH=2.25 </em></h3>

Explanation:

monochloroacetic acid  also means: chloroacetic acid

pKa of monochloroacetic acid= 1.4 x 10^-3  (I believe this should have been given in the problem or perhaps in the textbook)

Formula: pH= pKa + log ( some number in M)

pH= -log (1.4 x 10^-3) + log (0.25M)= 2.85 + -0.602= 2.25

pH= 2.25
