How many grams are 4.5 moles of NH3?

Answer 1

Here is the solution,
for 1mole NH3 or ammonia,
N: 14.0067 g/mol x 1
H: 1.00794 g/mol x 3
So approximately it is--> 17.03052 g/mol)


Now multiply this into 4.5 for 4.5 moles of ammonia, --> 4.5x17.03052 =76.64g

Answer 2

4.65 g HF * 1mol HF * 2 mol NH3 * 17.04g NH3

------------ ----------- ----------- --------- = 1.32 g NH3

20.01g HF 6 mol HF 1 mol NH3

Answer 3

I mole of ammonia is 17g, so 4.5 moles are 76.5g

Answer 4

This mass is 76,6395 g.

Answer 5

3,13 g hydrogen are needed.
