Question

calculate the molecular mass of -1) ammonia gas 2) oxygen ​

Answer 1

Answer:

sorry dont know the answer

Explanation:

Answer 2

Answer:

ammonia= 17g/mol

Oxygen= 8g/mol

Explanation:

Ammonia or NH3 has one nitrogen atoms and 3 hydrogen atoms

so, molecular mass= nitrogen+3hydrogen

=14 + 3 [1 hydrogen gas one molecular mass]

= 17 g/mol

And

mass of oxygen is 8
