Question

222 g of MTBE (CO(CH3)4) are added to gasoline, resulting in a total volume of 2 L
of reformulated gas (RFG). (Note: RFG consists of the native gasoline plus the MTBE
additive.) Assume that the density of RFG is 0.70 g/mL, and the density of MTBE is 0.74 g/mL.
For a-d, determine the concentration of MTBE in the RFG solution in the following units
a. mg/L
b. moles/L
c. % (w/w)
d. % (v/v)
e. What is the % (w/w) oxygen in the RFG due to MTBE?
