Question

Making Sugars for RNA Ribose, the sugar found in RNA, has been detected in experiments designed to mimic the conditions of early Earth. If ribose contains 40.00% C, 6.71% H, and 53.28% O, with a molar mass of 150.13 g/mol, what are the empirical and molecular formulas for ribose?

Step 1

For C: $\frac{40.00\,\text{g}}{12.01\,\text{g/mol}} = 3.33\,\text{mol}$ For H: $\frac{6.71\,\text{g}}{1.01\,\text{g/mol}} = 6.64\,\text{mol}$ For O: $\frac{53.28\,\text{g}}{16.00\,\text{g/mol}} = 3.33\,\text{mol}$ Show more…
