Naturally occurring silver has two isotopes. isotope a has a relative mass of 106.9051 and an abundancy 51.82%. isotope b has a relative mass of 108.9047. calculate the atomic mass of silver from these data

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.
