Ans c)
The density of oil is lesser than water whereas vinegar is a solution of acetic acid in water so denser than water.
Density is given as : mass / volume
Since here bottle is same , so the volume remains same . So the bottle with vinegar (higher density) only will have more mass than the bottle filled with oil only.
Add Answer to:
c) Which would have more mass-a bottle filled with oil only or the same bottle filled...

Lab 24 Part 2: Materials- 2 glass bottles, metal utensil Methods- One bottle was filled about a quarter with water. The bottle was gently tapped at the top with a metal utensil. Gradually the bottle was filled with more water and the sound was observed as it became more filled. The same experiment was done again but instead it was blown across the top to create a sound. Then a partner blew on the top of an empty bottle while...

1. Assume that your vinegar contained a small amount of citric acid (a triprotic acid). Using the same experimental data, would vou expect the molarity of this sample to be POST-LAB QUESTIONS the same as or different than a sample which contained only pure acetic acid? 2 Assume that the tip of your buret was not properly filled with NaOH solution. It contained an air bubble which was eliminated during the titration. Would the caleulated molarity of the vinegar be...

Here is a description of a familiar course of events; A glass bottle filled with water was placed in the freezer. Sometime later it was found that the water had frozen and the glass bottle had cracked open. In answering the following questions, cite evidence from the above description and experiments you have performed in the laboratory. Upon freezing, did the volume of the water increase, decrease, or remain the same? Upon freezing, did the mass of the water increase,...
I have filled in two glass gas bulbs with the same pressure of two different gasses:...
I have filled in two glass gas bulbs with the same pressure of two different gasses: hydrogen gas (H2) and propane gas (CH,CH,CH3). The gas bulbs have the same volume and are also kept at the same temperature. Which of the two bulbs contains more molecules of gas? Select one: a. The bulb filled with propane contains more molecules, because propane has a greater molar mass than hydrogen b. The bulb filled with propane contains more molecules, because one propane...

Suppose you have two balloons--one filled with hydrogen and the other with chlorine at the same temperature. If both balloons have the same number of molecules, which of the following statements is true? A. The balloons have the same density. B. The balloons have the same volume. C. The average speed of the gases is the same. D. The balloon filled with hydrogen has more atoms than the balloon filled with chlorine.

Estimate H if the bottle is kept at 13 °C Wine bottles are never completely filled:...
Estimate H if the bottle is kept at 13 °C Wine bottles are never completely filled: a small volume of air is left in the glass bottle's cylindrically shaped neck (inner diameter d- 18.5 mm) to allow for wine's fairly large coefficient of thermal expansion. The distance H between the surface of the liquid contents and the bottom of the cork is called the "headspace height (Figure 1), and is typically H 1.5 cm for a 750-mL bottle filled at...
