An analytical chemist has determined by measurements that there are 0.029 moles of oxygen in a sample of acetic acid. How many moles of hydrogen are in the sample?

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
