In the laboratory a student named Georgia weighed 4.75 g ofan unknown solid mixture containing benzoic acid, copper (II)sulfate, and sand. She added 15 mL of acetone to her sample and dissolved one of the components of the mixture.

She then filters this component to seperate ifout from the others (still dissolved insolution). She weighs thecomponent and finds it to weigh 2.65 g.

1. What is the percent composition of this component in themixture?

She then weighs this water-soluble component and finds ithas a mass of 2.20 g.

2. What is the percent composition of this component in themixture?

The third component was insoluble in both acetone andwater. Drying and weighing this component she it finds it has amass of 0.46 g.

3. What is the percent composition of this insuluble component of the mixture?
