Find the mass in grams of each element. 2. Find the number of moles. 3. Find the simplest ratio of moles. Question 1. Mass of elements in g. 2. Number of moles of each element. 3. Simple ratio of elements. Practice problems * A 2.765 g sample of lead oxide was heated in a stream

structure is derived. Firstly it is important to determine the percentage composition of elements to work out the empirical formula. The empirical formula was found to be C10H12O and the mass of the unknown was 148.09 m/z which when calculating the molecular weight of the empirical formula it did equal 148.09 g mol -1. This means that the empirical formula is also the molecular formula. As 12.01x10 carbons +1.008x12 hydrogens + 16= 148.09 09 g mol -1. From this knowledge the unknown molecule must include

Cost‚ Volume‚ and Profit Formulas All businesses require becoming profitable or at some point they will fail. Accounting plays an essential role in determining if the company will become successful and continue to do so over time. Using well-defined formulas in order to assess the exact numbers will facilitate the actions a company needs to carry out in order to maintain its goals. The accounting department would look at the cost-volume-profit analysis to concentrate on the different components
