Question

5. A mixture of 2.00 g of fluorine gas and 2.00 g of nitrogen gas is placed in a 15.0 L vessel at 50 °C. What is the partial pressure of each gas and what is the total pressure of the mixture? Be sure to include dimensional analysis and consideration of significant figures in your work. Also explicitly show any algebraic steps you use. 6. Find the frequency (in Hertz) of an electromagnetic wave with a wavelength of 95.1 nm. Be sure to include dimensional analysis and consideration of significant figures in your work.

Explanation / Answer

mol of F2 gas = mass/MW = 2/37.9968064 = 0.0526

mol of N2 gas = mass/MW = 2/28 = 0.07142 mol

V = 15 L, T = 50°C = 50+273 = 323 K

find Partial Pressure

PV = nRT

P = nRT/V

P-F2 = 0.0526*0.082*323 / 15 = 0.0928 atm

P-N2 = 0.07142 *0.082*323 / 15 = 0.12610 atm

Q6

WL = 95.1 nm

WL = 95.1*10^-9 m

WL = c/v

v = c/WL = (3*10^8)/( 95.1*10^-9) = 3.154*10^15 Hz
