A sample of Hydrogen gas has a volume of 25.5 liters at a pressure of 15.0 kPa. If the temperature is kept constant and the pres
patriot [66]

Answer:

<h2>7.65 litres </h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

P_1V_1 = P_2V_2

Since we're finding the new volume

V_2 =  \frac{P_1V_1}{P_2}  \\

15 kPa = 15,000 Pa

50 kPa = 50,000 Pa

We have

V_2 =  \frac{15000 \times 25.5}{50000}  =  \frac{382500}{50000}  \\  = 7.65

We have the final answer as

<h3>7.65 litres </h3>

Hope this helps you
