Answer:
See attachment for flowchart
Explanation:
The flowchart is represented by the following algorithm:
1. Start
2. Input Mass
3. Input Volume
4 Density = Mass/Volume
5. Print Density
6. Stop
The flowchart is explained by the algorithm above.
It starts by accepting input for Mass
Then it accepts input for Volume
Step 4 of the flowchart/algorithm calculated the Density using the following formula: Density = Mass/Volume
Step 5 prints the calculated Density
The flowchart stops execution afterwards
Note that the flowchart assumes that the user input is of number type (integer, float, double, etc.)
