Answer:

2.13 Kg/cm².

Explanation:

We'll begin by calculating the constant that exist between the pressure and the volume. This can be obtained by using the Boyle's law equation as shown below.

Boyle's law states that

PV = K

Where

P is the pressure.

V is the volume.

K is the constant.

We shall determine the value of K as follow:

Pressure (P) = 1.15 Kg/cm²

Volume (V) = 44.8 mL

Constant (K) =?

PV = K

1.15 × 44.8 = K

K = 51.52 Kg/cm²•mL

Finally, we shall determine pressure, when the volume is 24.2 mL. This can be obtained as follow:

Volume (V) = 24.2 mL

Constant (K) = 51.52 Kg/cm²•mL

Pressure (P) =?

PV = K

P × 24.2 = 51.52

Divide both side by 24.2

P = 51.52 / 24.2

P = 2.13 Kg/cm²

Therefore, the pressure is 2.13 Kg/cm².
