Add 500 ml of 1 M HCl solution to 500 ml of solution with 4.25g AgNO3 dissolved, a precipitate and filtrate are obtained. a) Calculate the mass of the precipitate obtained.
b) Calculate the molar concentration of the substance remaining in the filtered water. Assume that the volume of filtered water obtained does not change significantly.

Theoretical temperature at which molecules stop moving and no more heat can be removed from the object. kelvin: absolute zero degrees. none of the above.

The correct answer would be b) volume versus temperature, because they are also directly proportional.

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
