Hi + naoh -> h2o + nal

Answer: temperature? i hope this and have a wonderful

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

N= 3.2 moles, t = 50 + 273 = 323 k, p = 101.325 kpa, r = 8.314 l.kpa/k.mol pv = nrtv = nrt / p substituting.v = (3.2 mole)(8.314 l.kpa/k.mol )(323 k) / (101.325 kpa)hope this
