Question

a rock has a volume of 4.0cm3 and density of 3.0g/cm3. calculate the mass of the rock.​

Answer 1

Mass of the rock is equal to 12 g.

Here, according to the given information, we are given that,

Volume of the rock is equal to 4.0 cubic centimetres. Also, we are given that, the density of the rock is equal to 3.0 gram per cubic centimetres.

We have to find the mass of the rock.

Now, in order to find the mass of the rock, we need to utilize the formula that says,

Density is mass per unit volume.

Or, we can write it as, Density = $\frac{Mass}{Volume}$.

Now, by putting the values that have been given and placing them in the above formula, we get,

Density = $\frac{Mass}{Volume}$

Or, Mass = Density × Volume

Or, Mass = $(3.0).(4.0)$

Or, Mass = 12 g.

Hence, mass of the rock is equal to 12 g.
