Answer:

b. 6.02 x 1023 molecules

Explanation:

The formula mass of ammonia is 14 + 1 × 3 = 17.

The number of moles in 27.6g ammonia is 27.6 ÷ 17 = 1.62 mol.

A mole is 6.02 × 10²³, so the number of hydrogen atoms in a 1.62 moles of ammonia is 1.62 × 6.02 × 10²³ × 3 = 2.93 × 10² atoms.

At 25oC, three moles of a gas occupy a volume of 4.0 L at 1.9 kPa. If the volume increases to 12.0 L, what will the new pressure
givi [52]
The answer:
according to Boyle's law concerning Pressure (P), Volume (V), Temperature (T) and number of mole (n) , we have the famous formula:

PiVi = Pf Vf, 

Pi=1.9kPa
Vi= 4L
Vf = 12L
T=25
n=3 
Pf = ?
let's find the value of Pf
from the equation
PiVi   = Pf Vf  we can have Pf= PiVi  / Vf

Pf = 1.9*4 / 12 = 0.63

so the answer is <span>B. 0.63 kPa</span>
