Can someone help me with my chemistry P&D lab Problem stament: Your mom made some carrot juice and gave you a glass from it . upon drink it you realize that there is still residue left in it. You decide to use a filter paper to remove the residue but your mom said it is better to use cotton material. Plan and design an experiment to see which is better .

Hypothesis:The cotton material will better collect the carrot residue than the filter paper.

Aim:To determine if the cotton material will collect the carrot residue better than the filter paper.​

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
