Chemistry
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.

Ответ:
object B is more dense then Object A.
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 APut 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 BPut 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.Ответ:
