![]() ![]() These steps can be combined into one step. I will round to three significant figures at the end.ĭetermine the moles #"CO"_2"# that can be produced by multiplying moles #"Fe"_2"O"_3"# times the mole ratio between #"Fe"_2"O"_3"# and #"CO"_2"#. Next, using the periodic table, find the atomic mass in g/mol of each. I am keeping some guard units to reduce rounding errors. The first step to finding the molar mass of Ammonium Nitrate is to count the number of each atom present in a single molecule using the chemical formula, NO3NH4: Element Number of Atoms N (Nitrogen) 2: O (Oxygen) 3: H (Hydrogen) 4: 2. Counting the number of atoms of each element in the compound. On a previous question with the same equation, you indicated that the amount of hematite #("Fe"_2"O"_3")# is #"1.00 kg"#.ĭetermine the Molar Masses of #"Fe"_2"O"_3"# and #"CO"_2"# Multiply the subscripts times the molar mass of each element (atomic weight on the periodic table in g/mol), and add them. Finding the atomic masses of elements in the periodic table. ![]()
