I have a chemistry question: What would be the % composition of sugar in a drink mix solution if 35.0 g of the mix was dissolved in 70.0 g of water. (Assuming that the drink mix is all sugar)

Consider the following multistep reaction: a b→ab(slow) a ab→a2b(fast)−−−−−−−−−−−−−−−−− 2a b→a2b(overall) based on this mechanism, determine the rate law for the overall reaction. express your answer in standard masteringchemistry format. for example, if the rate law is k[a]3[b]2 type k*[a]^3*[b]^2
