an object has a mass of 123 g and volume of 17cm3. calculate the density of the object

All you have to do is divide the mass over volume. You should also remember the formula, its very important.

D= M/G
Density= 17 cm³ / 123 g = ?

mass = volume x densit

Therefore, density = mass/volume but you didn't substitute corrrectly.
mass = 123 g
volume = 17 cc
So density = 123/17 = ?

To calculate the density of an object, you need to divide its mass by its volume.

Formula for density:
Density (D) = Mass (m) / Volume (V)

Given:
Mass = 123 g
Volume = 17 cm3

So, to find the density, substitute the values into the formula:

Density (D) = 123 g / 17 cm3

Now, divide the mass (123 g) by the volume (17 cm3) to get the density:

D = 123 g / 17 cm3

Calculating this division will give us the density of the object.
