Answer to Question #346575 in General Chemistry for Han

Question

How many grams of NO will be produced, if 1.93g of H2O are also produced in the reaction below? Show the solution?

4NH3 + 5O2 -----> 4NO + 6H2O

Answer 1

M_r (NO) = 30 g/mol;

M_r (H₂O) = 18 g/mol.

4NH₃ + 5O₂ = 4NO + 6H₂O

According to the above reaction, 6 mol (108 g) of H₂O is formed when 4 mol (120 g) of NO is formed. We find how many grams of NO are formed when 1,93 g of H2O are formed:

120g NO — 108g H₂O

X — 1,93g H₂O

X = 120 * 1,93 / 108 = 2,144 g

ANSWER: 2,144 g NO
