An ideal gas has a density of 1.25×10−6 g/cm3 at 1.00×10−3 atm and 40.0 ∘c. identify the gas. an ideal gas has a density of 1.25×10−6 at 1.0010 and 40.0 . identify the gas. nitrogen hydrogen oxygen neon chlorine argon

OXYGEN

Explanation:
                   As density is given as,

                                        d  = P M / R T
Solving for M,
                                        M  =  d R T / P      (1)
Data Given:
                   d  =  1.25 × 10⁻⁶ g/cm³  =  0.00125 g/L

                   R  =  0.08206 L.atm.mol⁻¹.K⁻¹

                   T  =  40 °C + 273  =  313 K

                   P  =  1.00 × 10⁻³ atm

Putting values in eq. 1,

   M  =  (0.00125 g.L⁻¹ × 0.08205 atm.L.mol⁻¹.K⁻¹ × 313 K) ÷ 1.0 × 10⁻³ atm

   M  =  32.10 g/mol

Result:
           Molecular Mass of O₂ is 32 g/mol.

Okay well gravitational energy is matter forced by gravity making energy though the kinetic energy then the electric energy produces electricity from the kinetic energy and the kinetic energy gets its energy from the gravitational energy. was that the answer you wanted or something else?
