(Round your answer to the tenths place.) % H Type numbers in the boxes. Part 1: 5 points Part 2: 5 points 10 points Question 8 Determine the empirical formula of a compound that contains 54.5% carbon, 9.2% hydrogen and 36.3% oxygen. When entering the formula place the elements in the following order: C, H, O. 10 points For subscripts, write the number after the element it corresponds to. For example, H,O should be written as H2O. What is the percent composition by mass of carbon in propane, C,H?
