The pressure of the gas = 40 atm
Further explanationGiven
200 ml container
P = 2 atm
final volume = 10 ml
Required
Final pressure
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
[tex]\tt \rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
Input the value :
P₂ = P₁V₁/V₂
P₂ = 2 x 200 / 10
P₂ = 40 atm

How many moles of nitrogen (N2) are needed to produce 9.60x10^24 molecules
of nitrogen dioxide (NO2)? *
The number of moles of Nitrogen : == 7.975
Further explanationGiven
9.60x10²⁴ molecules of nitrogen dioxide (NO2)
Required
The number of moles
Solution
Reaction
N2 + 2O2 → 2NO2
moles of NO2 :
= 9.6 x 10²⁴ : 6.02 x 10²³
= 15.95
From the equation, mol N2 :
= 1/2 x mol NO2
= 1/2 x 15.95
= 7.975
The number of molecules :
= 8 x 6.02 x 10²³
= 4.816 x 10²⁴
