Question

1. hitunglah volume masing-masing gas berikut pada keadaan standar (STP)
a).34 gram gas NH3 amoniak
b).11 gram gas CO2
c). 100 gram gas SO3
Diketahui (n=14, o=16, n=1, s=32)

Tolong dijawab yah!! dengan cara-caranya:)

Answer 1

Volume gas = 22.4 liter per mol,
Mr NH3= 17
NH3 = 34 gram / 17 g/mol = 2 mol
2 mol x 22.4 liter = 44.8 liter
coba pake rumus itu buat nyari volume yg lainnya.

Answer 2

A) Mr NH₃ =  17
mol NH₃ = gr/Mr = 34/17 = 2 mol
V = mol x 22,4 = 2 x 22,4 = 44,8 L

b) Mr CO₂ = 44
mol CO₂ = gr/Mr = 11/44 = 0,25 mol
V = mol x 22,4 = 0,25 x 22,4 = 5,6 L

c) Mr SO₃ = 80
mol SO₃ = gr/Mr = 100/80 = 1,25 mol
V = mol x 22,4 = 1,25 x 22,4 = 28 L
