- 3.118 Consider common sugars such as glucose (C6H12O6) and sucrose (C12H22O11). What type of chemical bonding would you expect to find in these chemicals?arrow_forwardA compound associated with the odor of garlic on a persons breath has the chemical formula CyH8S and a formula mass of 88.19 amu. What number does y stand for in the chemical formula of the compound?arrow_forwardWhat number of atoms of nitrogen are present in 1.00 g of each of the compounds in Exercise 51?arrow_forward
- 1. Which of the following hydrocarbons has the highest mass percentage of carbon? methane, CH4 ethane, C2H6 propane, C3H8 butane, C4H10arrow_forwardA compound with a molar mass of about 42 g/mol contains 85.7% carbon and 14.3% hydrogen. What is its molecular structure?arrow_forwardResearchers obtain the following data from experiments to find the molecular formula of benzocaine, a local anesthetic, which contains only carbon, hydrogen, nitrogen, and oxygen. Complete combustion of a 3.54-g sample of benzocaine with excess O2 forms 8.49 g of CO2 and 2.14 g H2O. Another sample of mass 2.35 g is found to contain 0.199 g of N. The molar mass of benzocaine is found to be 165 g/mol. Find the molecular formula of benzocaine.arrow_forward
- Look at the structural formula of the organic compounds below, name them and give a detailed analysis of their possible physical and chemical properties.arrow_forwardA natural product has the molecular formula C25H34O4. What is the mass of 3.31×108 molecules of this compound?arrow_forwardThe fuel tank of an automobile contains 62.0 kg of gasoline. If the gasoline reacts completely with excess oxygen (from the air) to form CO2 and H2O, what is the total mass of the products? For simplicity, assume that gasoline is comprised of 100% octane.(C8H18).arrow_forward
- A.How many moles of boron tribromide are present in 5.93 x 10^22 molecules of this compound? B.How many molecules of boron tribromide are present in 1.38 moles of this compound?arrow_forwardThe recommended daily allowance of the niacin (vitamin B3) is 16 mg per day for man. The molecular formula for niacin is C6H5NO2. Calculate the number of molecules of niacin in 16 mg.arrow_forwardWhat are the molecular and empirical chemical formulas of a compound made up of these molecules? The lines stand for chemical bonds between the atoms. You can ignore the dots -- they represent "lone pairs" and you'll learn about them later.
