Question

1. You purchase 9.3 gallons of gasoline. Assume that the properties of gasoline are Molecular weight (Mw) = 113, Specific Gravity (SG) = 0.70. Remember that the density of water is 62.4 lbm/ft^3. What is the weight in lbf of the gasoline? and how many g ? moles are there in this quantity of gasoline?

2. Recall that the ideal gas law is P V = nRT where P is pressure, V is volume, n is number of moles, R is a constant, and T is the temperature.

(a) What are the dimension of R in terms of the base dimension types (length, time, mass, and temperature)?

(b) Show how these two values of R are equivalent: R = 0.0821 L?atm/mol*K = 8.31 J/mol*K

(c) If an ideal gas exists in a closed container with a molar density of 0.03mol/L at a pressure of 0.96 ? 10^5 Pa , what temperature is the container held at?
