Question

Calculate the change in mass of the eggs between the time they were placed in the water or corn syrup and 24 hours later when they were removed. Make a bar graph showing the results. The eggs may have undergone a positive or negative change in mass. Therefore, construct the bar graph with the zero change in mass in the middle of the y-axis. Which of the following options represents the correct calculation? 1) Subtract the initial mass from the final mass 2) Add the initial mass to the final mass 3) Multiply the initial mass by the final mass 4) Divide the initial mass by the final mass

Answer 1

To calculate the change in mass of the eggs, subtract the initial mass from the final mass. Then, plot each egg's change in mass on a bar graph with zero at the center of the y-axis.

Step-by-step explanation:

To calculate the change in mass of the eggs between the time they were placed in the water or corn syrup and 24 hours later when they were removed, you will need to subtract the initial mass from the final mass. This is represented by option 1 from your list. To construct a bar graph to demonstrate these results, you'll want to plot each egg along the x-axis and the change in mass along the y-axis, with zero change in mass at the center of the y-axis.

For example, if an egg initially weighed 65 grams, and after 24 hours in water weighed 70 grams, the change in mass would be 70 grams (final mass) - 65 grams (initial mass) = 5 grams.

A positive value would indicate an increase in mass (the egg absorbed water or corn syrup), while a negative value would indicate a decrease in mass (the egg lost water to its surroundings). By representing multiple eggs' mass changes on a single bar graph this way, you can visually compare how each egg was affected by the immersion.
