The sugar molecule 2-deoxyribose is the basic constituent of deoxyribonucleic acid (DNA). The mass percent composition of 2-deoxyribose is 44.77% carbon, 7.52% hydrogen and oxygen. If 50g of 2-deoxyribose contains 2.2456 x 1023 molecules, calculate its empirical and molecular formula.

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
