When 2.50 g of a zinc strip were placed in an AgNO[tex]\(_3\)[/tex] solution, silver metal formed on the surface of the strip. After some time had passed, the strip was removed from the solution, dried, and weighed. If the mass of the strip was 3.37 g, calculate the mass of Ag and Zn metals present.

To solve this problem, let's proceed step by step.

1. Initial Mass of Zinc Strip:
- This was given as 2.50 g.

2. Final Mass of the System:
- This was measured to be 3.37 g after the reaction and drying.

3. Mass of Silver Deposited:
- To find the mass of silver deposited on the zinc strip, we need to subtract the initial mass of the zinc strip from the final mass of the system.
- Final Mass of System = 3.37 g
- Initial Mass of Zinc = 2.50 g
- Mass of Silver Deposited = Final Mass of System - Initial Mass of Zinc
- This calculates to 3.37 g - 2.50 g = 0.87 g

4. Mass of Zinc Remaining:
- Since the problem doesn't mention any zinc being dissolved and removed from the strip, we will assume that the mass of zinc remains the same.
- The mass of zinc remaining is the initial mass of the zinc strip: 2.50 g.

Therefore, the mass of silver (Ag) deposited on the strip is 0.87 g, and the mass of zinc (Zn) remaining is 2.50 g.
