Question

question 5. oil and water are added to a beaker. the beaker in the figure below shows the oil and water after they have separated.
which of the following is an inference that explains the result of the experiment represented by the figure?
a) oil sinks in water.
b) oil is less dense than water.
c) water floats on oil.
d) water is less dense than oil.
question 6. what is the formula used to calculate mass from given density and volume?

Explanation:

Question 5

Density determines buoyancy. Less - dense substances float on more - dense ones. Since oil floats on water in the experiment, it implies that oil has a lower density than water.

The formula for density is \(
ho=\frac{m}{V}\), where \(
ho\) is density, \(m\) is mass, and \(V\) is volume. To find mass (\(m\)), we can rearrange the formula.

Answer:

B. Oil is less dense than water.
