A molecular formula expresses the number of each kind of atom in a molecule. For example, the molecular formula for propene, C3H6C3H6, indicates three carbon atoms and six hydrogen atoms per molecule. This also means that one mole of propene contains three moles of carbon and six moles of hydrogen.An empirical formula expresses the mole ratio of the elements. The empirical formula for propene is CH2CH2, indicating twice as much hydrogen as carbon. When analyzing unknown compounds in a lab, it is often possible to identify the mole ratios, and thus the empirical formula, but not the molecular formula.Notice that the molecular mass of propene, 3(12)+6(1)=42amu3(12)+6(1)=42amu, is a multiple of the empirical formula mass, 1(12)+2(1)=14 amu An unknown compound contains only carbon, hydrogen, and oxygen (CxHyOzCxHyOz). Combustion of 6.50 gg of this compound produced 9.53 gg of carbon dioxide and 3.90 gg of water. Part A How many moles of carbon, CC, were in the original sample?…

Imagine that all our balances displayed mass in units of slugs instead of grams. Would we still want to use the number , 6.022×10236.022×1023, for Avogadro's number? Why or why not? Yes, because the number of particles in one mole does not depend on the mass of the particles. No, because we would use the number of atoms in exactly 12 slugs of carbon-12 to define the mole. Yes, because the value of Avogadro's number is a universal constant. No, because we would not be able to use carbon-12 to define the mole. What number would we want to use instead? (A slug is equal to 14954 g.) Express your answer using four significant figures.

Assuming gasoline to be pure 2-methylhexane, C7 H16 (actually, it is a mixture of many substances), an automobile getting 26.5 miles per gallon would consume 5.96 x 1023 molecules per mile. Calculate the mass of this amount of fuel. Mass = g
