Answer:

The new pressure of a gas initially at 575 mmhg and 12500ml and the volume changed to 15L is 479. 16 mmHg

Step-by-step explanation:

Boyle's law states that the pressure of a given quantity of gas varies inversely with its volumes at constant temperature. It is represented as;

P V = K

P1 V1 = P2 V2

Where;

P1 = Initial pressure = 575 mmHg

P2 = Final pressure?

V1 = Initial volume = 12500ml = 12500÷ 1000 = 12.5 Liters

V2 = Final pressure = 15 Liters

Calculations :

P2 = P1 V1 ÷ V2

P2 = 575 × 12.5 ÷ 15

P2 = 7187 . 5 ÷ 15

P2 = 479. 16 mmHg

Therefore, the new pressure is 479. 16 mmHg
