Answer:
3.8 x 10⁵
Explanation:
For the equilibrium : 3NO(g) ⇌ N2O(g) + NO2(g), the equilibrium constant in the terms of the concentrations of the gases in mol/L is
Kc = (NO) (N2O)/ (NO) ³ where (NO), (N2O) , (NO2) are the concentrations of the gases in mol/L . So
K= (x mol/ 1 L) (x mol/1L) / (7.5 x 10⁻⁶ mol /1 L) ³
x = mol of NO and NO2 at equilibrium
we have that
K = x²/ 7.5 x 10⁻⁶ = 1.9 x 10¹⁶
x = √ (7.5 x 10⁻⁶ x 1.9 x 10¹⁶) = 3.8 x 10⁵
∴ (N2O) = 3.8 x 10⁵

Answer:
46.784886 amu is the average atomic mass of titanium on that planet.
Explanation:
Fractional abundance of Ti-46 =72.000% = 0.72000
Atomic mass of Ti-46 = 45.95263 amu
Fractional abundance of Ti-48 =14.300% = 0.14300
Atomic mass of Ti-48 = 47.94795 amu
Fractional abundance of Ti-50 =13.700% = 0.13700
Atomic mass of Ti-50 = 49.94479 amu

Average atomic mass of titanium atom:

46.784886 amu is the average atomic mass of titanium on that planet.
