Question

Halfway through his Conservation of Mass experiment, a Joe E. Cool realized that he

forgot to weigh his crucible after heating it. Short of starting over, what can Joe do to

ensure accurate results? Be specific and detailed in your answer.

Joe burned his magnesium sample and obtained a light gray product. Since his

crucible looked dirty anyway Joe skipped the step of heating to constant mass,

weighed the gray sample, and calculated the mass of the product. Was his resulting

mass likely to be high or low?

basically there will be a decrease in weight due to the left over.

if u want the weight of the crucible weigh with the crucible and substract the weight of the weight of grey sample.
