Question

Silver was precipitated and collected by filtration. The experiment yielded .077g of silver after dying. The predicted yield was .083g. The percent error present in the collection would be ?

Answer 1

Answer:

Precentage error = 7.23%

Explanation:

The precentage error formula  is the  useful method  for determining precision of your experimental result

It can be calculated using :

$percent\ error = |\frac{experimental\ value-predicted\ value} {predicted\ value}|\times 100$

$percent\ error = |\frac{0.077\ -0.083} {0.083}|\times 100$

So we get percentage error =  7.23%

Precision means how close the experimental value to the true value or theoretical value

If percentage error is large it means experimental results are deviated and there is need to check mistakes,imprecision in the experiment

If the percentage error is zero it means the experiment is perfectly done without  inaccuracy
