chem1b_lesson12_2_chemical_calculations_reagangriffin.docx - Lesson 12. ... Using to the periodic chart, we can find that 1 mole of N2has a mass of 28 g. (2 N × 14.0 g/mole = 28 g/mole N2.) We know that one mole of H2 is 2.02 g/mole. (2 H × 1.01 g/mole = 2.02 g/mole H2). Our ratio is 7 g N2/ 28 g/mole N2= (X)/ (3 moles) (2.02 g/mole H2). Cross multiply and the answer is 1.52 g H2.
