Concept explainers

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can b…

Phosphoric acid, one of the acids used in some cola drinks, is produced by the reaction of phosphorus(V) oxide, an acidic oxide, with water. Phosphorus(V) oxide is prepared by the combustion of phosphorus.

(a) Write the empirical formula of phosphorus(V) oxide.

(b) What is the molecular formula of phosphorus(V) oxide if the molar mass is about 280.

(d) Determine the mass of phosphorus required to make 1.00 × 10 4 kg of phosphoric acid, assuming a yield of 98.35%.

3. An unknown element, X, combines with chlorine to give a substance with the formula XC14. A chlorine analysis of the substance indicates that it contains 83.47% chlorine by mass. What element is X and what is the formula of this compound? (Hint: to identify an element or compound, identify its molar mass. Remember that Molar Mass = (grams A)/(moles A). Solve for each individually and then divide them to find molar mass.)

1. When hydrogen sulfide (H2S, MM = 34.08 g/mol) gas is bubbled into a solution of sodium hydroxide (NaOH, 40.00 g/mol), sodium sulfide (Na2S, 78.04 g/mol) and water (18.02 g/mol) are produced according to the balanced chemical equation shown below? H2S 2 NaOH --> Na2S 2 H₂O (a) Assuming the reaction goes to completion, how many grams of sodium sulfide are formed if 2.50g of hydrogen sulfide is bubbled into a solution containing 1.85g of NaOH? (20 pts) (b) Which reactant and how much of it remains after the reaction has been completed? (15 pts) (c) If only 0.400g of sodium sulfide was recovered, what is the percent yield of this reaction (5 pts)

The organic compound MTBE (methyltertiarybutylether) is used as a fuel additive that allows gasoline to burn more cleanly thus leading to a reduction in pollution. Recently, however, MTBE has been found in the drinking water of a number of communities. As a result several states are phasing out the use of MTBE as a fuel additive. A combustion experiment using 10.00 g of MTBE was found to produce 24.97g of CO2 and 12.26 g of H2O. (a) What is the empirical formula of MTBE assuming it contains C, H, and O only? (b) The molar mass of MTBE was experimentally determined to be 88.1 g/mol. Using this information what is the molecular formula of MTBE
