Suppose the object moves with
11. Air bags in automobiles inflate when sodium azide, NsN, rapidly decomposes to its component elements 2NaNj(s) 2Na(s) + 3N2(g). (a) How many moles of N2 are formed by the decomposition of 1.60 mol of NaNy? (b) How many grams of NaN, are required to form 7.00 g of N2 gas? 12. A 5.325 g sample of methyl benzoate, a compound in perfumes, was found to contain 3.758 g of carbon, 0.316 g of hydrogen, and 1.251 g of oxygen. What is the empirical formula? If its molar mass is about 130 g/mol, what is its molecular formula? An analysis of an oxide of nitrogen with a molecular weight of 92.02 amu has a percent composition of 69.57% oxygen and 30.43% nitrogen, what are the empirical and molecular formulas for this nitrogen oxide? Complete and balance the equation for its formation from the elements nitrogen and oxygen. 13. 14. How many sodium atoms are in 0.1310 g of sodium? Copyright O 2015 Pearson Education, Inc.
