Question

If 2 objects have the same volume of 10cm3 and object A has a mass of 2 grams and object B has a mass of 4 grams, how do their densities relate to one another?

I need a step by step explanation also. I don’t fully understand the subject.

Answer 1

object B is more dense then Object A.

Step-by-step explanation:

Data Given:

Volume of object A = 10cm³

Volume of object B = 10cm³

mass of object A = 2 g

mass of object B = 4 g

density of object A and B = ?

Solution:

This question is about to calculate density of two objects that have same volume. object may be a gas or liquid or any chemical.

these two objects have different masses.

We first have to calculate the densities of these to objects to relate it because have same volumes.

Formula for density Calculation

d = m/V

• now to calculate density of object A

Put values for object A in the formula

d = m/V

d = 2 g / 10cm³

d = 0.2 g/cm³

• now to calculate density of object B

Put values for object B in the formula

d = m/V

d = 4 g / 10cm³

d = 0.4 g/cm³

Now

we come to Know that

density of object A = 0.2 g/cm³

and

density of object B = 0.4 g/cm³

So, these two objects have same volume but different masses so it have different densities.

So,

• density of object B is more as its mass is more than object A,
• Object A's density is less as its mass is less than object B.

• Object B is more dense than Object A, as their masses are different.
