7. [-/0.26 Points] DETAILS At a temperature of 20C, the volume V (in liters) of 1.33 g of O2 is related to its pressure p (in atmospheres) by the formula V(p) = P (a) What is the average rate of change of V with respect to p when the pressure is changed from p = 6 to p = 9? L/atm (b) What is the average rate of change of V with respect to p when the pressure is changed from p = 6 to p = 7? L/atm (c) What is the rate of change to V with respect to p when p = 6? L/atm Show your work by completing the four-step process. (Simplify your answers completely for each step.) Step 1: V( 6 + h ) = Step 2: V(6 + h) - V(6) = (Hint: Express your answer as a single fraction.) V(6 + h) - V(6) Step 3: S h Jhy Step 4: V ' (6) = lim V(6 + h) - V(6) h -0 h
