Answer to Question #25352 in Inorganic Chemistry for Amanda
A sample of hydrogen gas (H2) has a volume of 17.4 L at a temperature of 0°C and a pressure of 1.60 atm. The number of moles of H2 molecules of hydrogen in the sample is
The ideal gas law can be used for solving this question:
PV = nRT
n is amount = ?
P is pressure = 1.60 atm = 162.12 kPa
V is volume = 17.4 L
R is gas constant = 8.31
T is temperature = 0°C = 273K
n = PV/RT
n = 162.12 * 17.4 / (8.31*273) = 1.24 mol
