What is the final step in the fourth stage of technological design, after a product has been improved and approved? reporting the results finding ways to lower costs selling a prototype determining criteria

Answer;

A - reporting the results

Explanation;

-Steps of the technological design process include: identify a problem, research the problem, generate possible solutions, select the best solution, create a model, test the model, refine and retest the model as needed, and communicate the final solution.

-Technological design is similar to scientific investigation. Both processes rely on evidence and reason, and follow a logical sequence of steps to solve problems or answer questions.

-In the last stage of the technology design process, engineers must communicate to consumers how a product meets their needs. They must also communicate with those involved in bringing the product to consumers.

A: Reporting Results

Explanation:

The last stage of the technological design process is reporting the results of the product.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
