A student finds a rock on the way to school in laboratory he determines that volume of is 22.7 ml and mass 39.943 g what desity rock?

Given:

- Volume of the rock, \(V = 22.7 \texttt{ ml}\)

- Mass of the rock, \(m = 39.943 \texttt{ g}\)

To find:

- Density of the rock, \(\rho\)

Formula:

The density of an object is defined as its mass per unit volume. Mathematically, it can be expressed as:

$$\rho = \frac{m}{V}$$

where:

- \(\rho\) is the density in \(\texttt{g/ml}\)

- \(m\) is the mass in \(\texttt{g}\)

- \(V\) is the volume in \(\texttt{ml}\)

Calculation:

Substituting the given values into the formula, we get:

$$\rho = \frac{39.943 \texttt{ g}}{22.7 \texttt{ ml}} = 1.76 \texttt{ g/ml}$$

Therefore, the density of the rock is \(1.76 \texttt{ g/ml}\).
