Question

If 25 mL of each of the liquids in the answer choices below were poured into a 100 mL beaker, which would form the second from the bottom layer? A. sea water – density of 1.024 g/mL B. mineral oil – density of 0.910 g/mL C. distilled water – density of 1.0 g/mL D. petroleum oil – density of 0.820 g/mL

Answer 1

Option B. mineral oil – density of 0.910 g/mL C.

Step-by-step explanation:

From the question, we obtained the following information:

sea water – density of 1.024 g/mL

mineral oil – density of 0.910 g/mL

distilled water – density of 1.0 g/mL

petroleum oil – density of 0.820 g/mL

To which will be at the bottom, their densities will play a major role.

When we mix all together,

Sea water and distilled water will form uniform layer bcos they both water but the remaining liquids will form various layer.

Since water is denser than all the liquid, it will remain at the bottom, followed by the mineral oil(less dense than water) and then petroleum oil.

From the above illustration, mineral oil will be the second layer from the bottom.
