Given the following sets of values for three of the gas variables, calculate the unknown.
P = ? mm Hg; V = 26.0 mL; n = 0.007826 mol; T = 15.6°C
If a gaseous mixture is made of 2.37 g of He and 2.73 g of Ne in an evacuated 1.19 L container at 25°C, what will be the partial pressure of each gas and the total pressure in the container?
2 answers
Use PV = nRT for He (n = gram/molar mass) and solve for pHe.
Do the same for Ne, then add the partial pressures to obtain total pressure.
#2 use PV = nRT
Do the same for Ne, then add the partial pressures to obtain total pressure.
#2 use PV = nRT
