Step 1) Write and balance chemical equation N2(g) + 3H2(g) --------------> 2NH3(g) Step 2) Use dimensional analysis, or set a proportion to see how many mol H2 are needed. Here, I use dimensional analysis. Start with the given (1.22molN2), multiply it by the values in mol from the balanced equation so that the units cancel out. 1.22molN2 * (3molH2 / 1molN2) = 3.66molH2 |
