Question

Chwal Dr. Maher EXTRA CREDIT Me organic compound MTRF (methyltaryuyether) is used as a fuel additive that allows Basoline to burn more cleanly thus leading to a reduction in pollution Recently, however MIBE has been found in the drinking water of a number of communities. As a result several States are phasing out the use of MTRE a fuel additive. A combustion experiment using 10.00 g of MTBE was found to produce 24.97g of Co, and 12.26 g of H2O (a) What is the empirical formula of MTRE assuming it contains C, H. and only? (b) The molar mass of MTBE was experimentally determined to be 88.1 g/mol. Using this information what is the molecular formula of MTBE

Answer 1

mans of c'= 24.97x12 = 6.81 er 44 mase of H = 12.26x2 = 1.36 g mass of '= 10.0 - [6.81 + 1.36] - 1.83q I more 16.81 = 0.5675 1 Simplest ratio Element I man 6.81 0.5675 = 5.0 12 0.114 H 1:36 1.36 11:36 = 12.0 136 1983 136 = 1.36 19:23 -0.114 0.114 ollu Empirical formula = CHIRO & Molecular tormula = nx Empirical formula ne 88.1 = 1 88.)
