The reaction N2 + H2 —-> NH3, if 2.00 grams of hydrogen reacts: how many grams of ammonia are
produced? How many grams of nitrogen react?

mass NH3 = 11.264 g

mass N2 = 9.264 g

Explanation:

balanced reaction:

∴ mass H2 = 2.00 g

∴ molar mass H2 = 2.016 g/mol

∴ molar mass N2 = 28.0134 g/mol

∴ molar mass NH3 = 17.031 g/mol

⇒ mol H2 = (2.00 g)*(mol/2.016 g) = 0.992 mol

⇒ mol NH3 = (0.992 mol H2)*(2 mol NH3/3 mol H2) = 0.6614 mol

⇒ mass NH3 = (0.6614 mol)*(17.031 g/mol) = 11.264 g

⇒ mol N2 = (0.6614 mol NH3)*(mol N2/2 mol NH3) = 0.3307 mol

⇒ mass N2 = (0.3307 mol)*(28.0134 g/mol) = 9.264 g

no

go away, people want answers, not to hook up

what is the question here. i think you messed up.
