Really need help!! Don’t understand:( 40 points If 100.0g of nitrogen gas (N2) is reacted with 100.0g of hydrogen gas (H2) what is the limiting and excess reactants?

Hint: convert grams to moles for each reactant and then convert to moles of NH3. You need your balanced equation from answer 1 to determine the mole relationship between each reactant and the product NH3. Use the periodic table to determine the molar mass of all chemical formulas. Fill in the “?” Blanks below to show your work.

Please please please fill in the blanks...

Molar mass of H2= g/mol

100.0g H2 • 1 mol H2/? g H2 • ? Mol NH3/ ? Mol H2 = ? Mol NH3

Molar mass of N2= ? g/mol

100.0g N2 • 1 mol N2/ ? g N2 • ? Mol NH3/ ? Mole N2 = ? Mol NH3

Molar mass of NH3 = ? g/mol

100.0g N2 • 1 mol N2/ ? g N2 • ? Mol NH3/ ? Mol N2 • ? g NH3/ 1 mole NH3 = g NH3

Pretty please help me :( PWEAAS
