If I have oxygen gas at a pressure if 36.0kpa a volume if 37l and a temperature of 82C how many moles of gas do I have

Sagot :

In order to find the number of moles in this question, we need to use the Ideal gas Law formula, which is the following formula:

PV = nRT

Where:

P = pressure, we will use it in atm, 36.0 kPa = 0.355 atm

V = volume in liters, 38 L

n = number of moles

R = gas constant, 0.082

T = temperature in kelvin, 82°C = 355 K

Now we add all these values into the formula:

0.355 * 38 = n * 0.082 * 355

13.49 = 29.11n

n = 0.46 moles of Oxygen gas
