What will the volume of 2.5 moles of gas be at 281K and 102 kPa?

Answer :

STRITEGO STRITEGO

Answer:

V = 57.23

Explanation:

Using the ideal gas law (PV = nRT), we plug in the variables for moles, Kelvin, and pressure: (102 * V = 2.5 * R * 281). We plug in the correct R constant value for the type of pressure we are using (atm, Kpa, or mmHg) with values of (0.0821, 8.31, or 62.4) respectively. Since we are using kPa in this example, we use 8.31 for the R constant so we get: (102 * V = 2.5 * 8.31 * 281). We solve the right side to get: (102 * V = 5837.775). We divide 102 sides from both sides to get that (V = 57.233)
