Presentation Transcript

### How many hydrogen molecules are present in 2.356 x 1019 moles of H2O?

### Arrange the following samples in order of increasing # of C atoms: (a) 12 grams C, (b) 1 mol C2H2, (c) 9 x 1023 molecules of CO2

### It is a chemical formula that tells us the ratio of atoms within the compound with the smallest integers.

### What is the step-by-step process that leads to the empirical formula from grams of each element?

### Grams of each element Use molar mass to convert Moles of each element Calculate mole ratio empirical formula

### Ascorbic acid contains 40.92% C, 4.58% H, and 54.50% O by mass. Find the empirical formula.

### What is the molecular formula of mesitylene if its molecular weight is 120 amu and its empirical formula is C3H4?

### Combusting .255 g of isopropyl alcohol produces .561 g of CO2 and .306 g of water. Determine the empirical formula of isopropyl alcohol.

### How many moles of H2O are formed when 6.79 grams of C2H4O2 are combusted in open air?

### How many grams of H are produced when 9.2 grams of C2H4O2 are combusted in air?

### What ratio is used to convert b/w amounts of reactants & products in a reaction?

### How many grams of NaOH form when 4.2 moles of Na2O and 4.2 moles of water combine?

### How many moles of sulfuric acid form when .356 grams of SO3 and 1.98 grams of water combine? What is the limiting reactant?

### How many liters of .36 M HCl does it take to react with excess Magnesium hydroxide to form 4.55 grams of Magnesium chloride?

### An empirical formula reflects the smallest ratio of atoms, while the molecular formula does not.

### How many molecules of Cl are in 9.67 x 104 grams of Magnesium chloride?

### If the empirical formula of a compound is C4H8O and the mass of the compound is 216 grams, what is the molecular formula?

### Final JeopardyWhat is the molecular formula of a compound with empirical formula CH4 and mass 144g?

### C9H36
