Propane (c3h8), a fuel that is used in camp stoves, produces carbon dioxide (co2) and water vapor (h2o) on combustion as follows. mc032-1. given that the molar mass of h2o is 18.02 g/mol, how many liters of propane are required at stp to produce 75g of h2o from this reaction

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
