A solution contains an unknown amount of dissolved calcium. Addition of 0.112 mol of K3PO4 causes complete precipitation of all of the calcium. How many moles of calcium were dissolved in the solution

Depends on the speed of the car.

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
