As the result of experimental work, a student finds the density of a liquid to be .137 g/ml. the known density of the liquid is .1478 g/ml. find the student's experimental error (ee) and percentage error (pe).

Respuesta :

the known density of the liquid is

[tex]d_known = 0.1478 g /ml[/tex]

the density of a liquid

[tex]d_calculated = 0.137 g /mol[/tex]

[tex]experimental error = d_known – d_calculated[/tex]

[tex]= 0.1478 – 0.137 = 0.0108 g /mL[/tex]

Thus, experimental error of 0.0108 g /mL is present.


[tex]Percentage error = [ (d_known – d_calculated) / (d_known) ] * 100[/tex]

[tex]=[ (0.0108) / 0.1478 ] * 100[/tex]

[tex]= 7.31 %[/tex]

Thus, Percentage error of 7.31 % is present.
