PPT-Simplest formula calculations

Q a compound is found to contain the following by mass 6958 Ba 6090 C 2432 O What is the simplest ie empirical formula Step 1 imagine that you have 100 g of the substance Thus will become mass in grams Eg 6958 Ba becomes 6958 g Ba Some questions. Section. 2.3. Writing Fractions in Simplest Form. Fractions that represent the same portion of a whole are called equivalent fractions. . There are many equivalent forms of a fraction. A special form of a fraction is called . Danielle DelVillano, Pharm.D.. 1. Objectives. Perform calculations to reduce or enlarge formulas for pharmaceutical preparations stated in metric quantities. Perform calculations to reduce or enlarge formulas for pharmaceutical preparations stated in proportional parts. Finding the Simplest Formula. Finding the Simplest Formula. Imagine you react 2.6512 g of Zn is reacted with excess Cl. 2(g). When the Zn and Cl. 2. have finished reacting a white powder is left and has a mass of 5.4512 g. Q: how long would it take to spend a mole of $1 coins if they were being spent at a rate of 1 billion per second?. Background: atomic masses. Look at the “atomic masses” on the periodic table. What do these represent?. page 3The 17c formula – Bad for Diminished Value calculationspage 6Auto Appraisal methods: Calculated and Measured Valupage 8 Components of 17c formulpage 8 1.
