Answer:
0.719 moles of NH₃
Explanation:
Molar mass of ammonia 17 g/mol

12.23 g / 17 g/mol = 0.719 moles
There are 9 polyatomic ions so which one and the compound “Sn(NO2)2 is Tin(ll) Nitrite
The law of definite proportions would state that a hydrate always contain exactly the same proportion of salt and water by mass.
strictly speaking, the law of definite proportion states that a compound always
contains exactly the same proportion of elements by mass.
But the law is often applied to groupings of elements in compound.
Hydrates are salt that have a certain amount of water asa part of their structure.
The water is chemically combined with the compound in a definite ratio.
