1. When a bracelet weighing 383 g in air is submerged in water, a scale measures a weight of 349 g. What is the density of the bracelet? Is the bracelet
made of pure gold or something else? Explain. (Use 1.00 g/cm'as the density
of water and 19.3 g/cm'as the density of pure gold.)

B. nuclear reactions could first occur.

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
