Which of the following planets has the lowest average density?1) Venus
2) Mercury
3) Earth
4) Mars

Please explain

Answers

The planet that has the lowest average density is Mars. The correct option is 4.

What is average density?

The entire mass of a region divided by the total volume of that region yields the mean or average density.

By multiplying each compound's density by its volume and then dividing the result by the sum of all the volumes, one can determine the mixture's average density.

The average density of different planets is:

Venus; 5.2

Mercury; 5.4

Earth; 5.5

Mars; 3.9

So, the lowest density out of these planets is Mars. Density is something's concentration. If the density is low, the weight of the object will be low. When placed in water, an object will float if its density is lower than that of the water, whereas it will sink if its density is higher.

Therefore, the correct option is 4) Mars.

Mars because it has low levels of gravity and if given the oppurtunity could float on water.
