The stems of bamboo can grow at a phenomenal rate of 0.3 m/day under optimal conditions (renewable resource!). Given that the stems are composed almost entirely of cellulose fibers oriented in the direction of growth, calculate the number of sugar residues per second that must be added enzymatically to growing cellulose chains to account for this rate. Each D-glucose unit contributes ~0.5 nm to the length of a cellulose molecule.
How do you solve for the molarity, molality, or mass percent of solute while only given two other bits of information
