The table shows a chemical equation and the dimensional analysis used by a student to calculate the number of moles of ba3n2 required to produce 9.2 moles of ba(oh)2. what is the error in the dimensional analysis? 1) 1 mol of ba3n2 should be replaced with 3 mol of ba3n2 2) 3 mol of ba(oh)2 should be replaced with 1 mol of ba(oh)2 3) 3 mol of ba3n2 should be interchanged 4) 9.2 mol of ba(oh)2 and 1 mol of ba3n2 should be interchanged.
