Answer to Problem 62A
18 g
Explanation of Solution
According to the question, ammonium nitrate
The mass of ammonium nitrate is given 40 g and that of nitrogen and oxygen is given 14 g and 8 g respectively. Here, the mass of water is not given and needs to be determined.
Total mass of the product formed is 40 g, thus, as per the law of conservation of mass, the total mass of reactant must be 40 g. This can be calculated as follows:
Substituting the values,
Rearranging,
Thus, the mass of water formed is 18 g.
