Explanation:

Equation of the reaction;

C4H10 + 13/2 O2> 4CO2  + 5H2O

Number of moles of Butane = 99.08g/58 g/mol = 1.71 moles

1 mole of Butane yields 4 moles of CO2

1.71 moles of Butane yields 1.71 * 4 = 6.84 moles Of CO2

Mass of CO2 = 6.84 moles Of CO2 * 44 g/mol = 300.96 g

5. Number of moles of butane = 290.38 g/58 g/mol = 5 moles

1 mole of butane yields 5 moles of water

5 moles of butane yields 5 * 5 = 25 moles of water

Mass of water = 25 moles of water * 18 g/mol = 450 g of water

6. Number of moles of butane = 307.47g/58 g/mol = 5.3 moles

1 mole of butane reacts with 6.5 moles of oxygen

5.3 moles of butane reacts with 5.3 * 6.5 = 34.45 moles of oxygen

Mass of oxygen = 34.45 moles of oxygen * 32 g/mol = 1102.4 g

7.  Number of moles of butane = 160.87/58 g/mol = 2.8 moles

1 mole of butane reacts with 6.5 moles of oxygen

2.8 moles of butane reacts with 2.8 * 6.5 = 18.2 moles of oxygen

Mass of oxygen = 18.2  moles of oxygen * 32 g/mol = 582.4 g

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
