A group of students are doing an analysis of copper in 1-peso coin. They were tasked to prepare standard solutions and weigh the analyte as the end-product of their experiment. Explain the type of error they are incurring in their experiment. A. Marikit had very good precision but poor accuracy in her data. B. Volumetric flasks were placed inside the oven for drying before it was used. C. Trial 1 and 2 have values close to 30.0 mL while trial 3 gave 55.0 mL. D. The reagent used in determining copper was added incorrectly and gave a low yield.A certain mineral contains the substance Cu(NO3)2 .Cu2SO4. Cu3N2. The copper present in a 1.5000g sample of this mineral is analyzed by adding aqueous ammonia to precipitate the copper as Cu(OH)2 and then incinerated and weighed as CuO. What is the weight percentage of Cu in this mineral if 0.85g of CuO were obtained? Please answer fast I give you upvote.
