How do you calculate % error in chemistry

Divide the error by the exact or ideal value (i.e., not your experimental or measured value). This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.

I feel like it is important, because it is always nice to learn about new things and keep your mind open, to expand your knowledge.

I hope this helps ^-^

Calculate the ph of a solution whose(oh^-) is 4.583*10^-5 mole dm cube (pkw=14)

Sergeu [11.5K]

pH of solution = 9.661

<h3>Further explanation </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

pOH=-log[OH⁻]

$\tt pOH=-log[4.583\times 10^{-5}]\\\\pOH=5-log~4.583=4.339$
