Answer:
8moles
Explanation:
We are given the mass of ammonia to be 136g
Ammonia = NH₃
Let us find the number of moles in ammonia;
Number of moles = 
Molar mass of ammonia = 14 + 3(1) = 17g/mol
so;
Number of moles = 
= 8moles
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen
It is caco3 ok thats the answer
