Answer:
Explanation:
To calculate for the percent error, determine the difference between the values given and divide by the true value,
(-655 - -603)/(-603) = 0.0862
Multiply by 100%,
(0.0862) x 100% = 8.62%
The pressure reading increases.
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit vicinity over which that pressure is distributed. Gauge stress (also spelled gage pressure)[a] is the stress relative to the ambient pressure.

Answer:
pH = 2.77
Explanation:
Data Given:
degree of dissociation Ka = 0.057
Concentration of Methanoic acid = 0.005 M
pH = ?
Solution:
First we calculate Hydrogen ion concentration
Formula will be used
[H⁺] = . . . . . . (1)
where
Ka = degree of dissociation
c = concentration
Put values in formula 1
[H⁺] = . . . . . . (1)
[H⁺] = 0.0017 M
Now Calculate the pH
As we know
pH = -log [H⁺] . . . . . .(2)
Put values in equation
pH = - log [ 0.0017 M]
pH = - [-2.77]
pH = 2.77
So,
pH of methanoic acid = 2.77
