The bulk modulus of water is `2.3 xx 10^(9) Nm^(-2)`.
(i) Find its compressibility.
(ii) How much pressure in atmosphere is needed to compress a sample of water by 0.1%

Explanation

To solve the problem step by step, we will address each part of the question separately.

### Part (i): Finding Compressibility

1. **Understanding Bulk Modulus (B)**: The bulk modulus \( B \) is defined as the measure of a substance's resistance to uniform compression. It is given by the formula:
\[ B = -V \frac{dP}{dV} \]
