How do I convert between nmol and ug of siRNA?

Use the molecular weight of siRNA to convert between nmol and ug. If the specific molecular weight is not known, you may use the average molecular weight of siRNA, which is 13,300 g/mol. If, for example, you have 5 nmol of siRNA, the conversion would be performed using the following steps: a. equation: ? ug = (5 nmol)(13,300 g/mol)b. unit conversions: ? ug = (5 nmol)(13,300 g/mol)(mol/10exp9 nmol)(10exp6 ug/g)c. answer: ? ug = 66. 5 ugTherefore, a 5 nmol quantity of siRNA is 66. 5 ug.
