How many grams of ammonia are formed when 1.34 grams of nitrogen react with an excess of hydrogen(3 H2 + N2 reacts to form 2 NH3)(Answer to tenths ex. 2.5)?
Write the equation and balance it.
N2 + 3H2 ==> 2NH3
Convert 1.34 g N2 to moles. moles = grams/molar mass.
Using the coefficients in the balanced equation, convert moles N2 to moles NH3.
Convert moles NH3 to grams. g = moles x molar mass. Round to the tenths place.
Post your work if you get stuck.
