Question

In the bouncy egg experiment with salt, how much salt do you need to achieve the desired effect?

A) 100 grams
B) 200 grams
C) 300 grams
D) 400 grams

Answer 1

To conduct the bouncy egg experiment, 150 grams of NaCl should be added to 2850 grams of water, allowing for an egg to float due to the increased density of the solution.

Step-by-step explanation:

In the bouncy egg experiment with salt, you would need to weigh out 150 g of NaCl (sodium chloride) to achieve the desired effect. To do this, you would add the salt to 2850 g of water. This amount of salt ensures that the solution's density becomes high enough for an egg to float. If we start with 3000 g of solution, we subtract the mass of the NaCl from the total to find the mass of water needed. The density of salt is a crucial factor here because it affects how much salt is required to alter the water's density sufficiently for the egg to bounce. So, for a bouncy egg experiment seeking a threshold where an egg can float, 150 grams of salt is optimal based on its solubility in water and ability to change the water's density.

Answer 2

To achieve the desired effect in the bouncy egg experiment with salt, you would need to use 150 grams of NaCl added to 2850 grams of water.

The answer is no matter the choice. Options A, B, C and D are none of the correct ones.
