6,67 points Calculate the approximate temperature in °C) of a 0.50 mol sample of gas at 750 mm Hg and a volume of 12 L.

Ithink ahopefully im correct 

Answer:             1.0  × 10⁻⁵ msolution:                     as we know ph is given as,                                    ph  = -log [h⁺]and,                                    [h⁺]  =  10^-ph    (1)putting value of ph in eq. 1,                                    [h⁺]  =  10⁻⁵                                    [h⁺]  =  1.0  × 10⁻⁵ m

The answer would have to be  reduce human impact on the environment
