There are 48 hydrogen atoms, 24 carbon atoms, and 12 oxygen atoms, also 12 molecules of acetaldehyde were produced in the reaction.
The equation of the reaction is;
12C2H4 + 6O2 ------> 12 CH3CHO
In order to approach this problem, the balanced reaction equation is the first step. There are 12 ethylene molecules and six oxygen molecules. These will combine as shown.
There number of atoms involved are as follows;
H = 48
C = 24
O = 12
There are 12 molecules of acetaldehyde produced in the reaction.

Answer:
Explanation:
First we need to find how many moles of ammonium weigh 62 grams.
Molar mass of NH4 = (14.0)+(4*1.0) grams
or 18.0 grams/mole
62 (g)/18(g/mole) = 3.444... moles of NH4
If it is dissolved in 5 litres of water, the concentration will be 3.444moles/5L
or 0.6888 M.
