The organic compound MTBE (methyltertiarybutylether) is used as a fuel additive thatallows gasoline to burn more cleanly thus leading to a reduction in pollution. Recently,however, MTBE has been found in the drinking water of a number of communities. As aresult several states are phasing out the use of MTBE as a fuel additive. A combustionexperiment using 10.00 g of MTBE was found to produce 24.97g of CO2 and 12.26 g ofH2O.(a) What is the empirical formula of MTBE assuming it contains C, H, and O only?(b) The molar mass of MTBE was experimentally determined to be 88.1 g/mol. Using thisinformation what is the molecular formula of MTBE

Approach to solving the question:(a) Empirical Formula of MTBE1. Given Data:Mass of MTBE: 10.00…

The carbon dioxide exhaled in the breath of astronauts is often removed from the spacecraft by reaction with lithium hydroxide 2LiOH(s)+CO2(g)Li2CO3(s)+H2O(l) Estimate the grams of lithium hydroxide required per astronaut per day. Assume that each astronaut requires 2.50 103 kcal of energy per day. Further assume that this energy can be equated to the heat of combustion of a quantity of glucose, C6H12O6, to CO2(g) and H2O(l). From the amount of glucose required to give 2.50 103 kcal of heat, calculate the amount of CO2 produced and hence the amount of LiOH required. The H for glucose(s) is 1273 kJ/mol.
