RNA conversions

Mass to Molesmoles ssRNA = mass of ssRNA (g)/molecular weight of ssRNA (g/mol) where, 1 g/mol = 1 Da (dalton)

Mass to MoleculesssRNA copy number = moles of ssRNA x Avogadro’s Number where, Avogadro’s Number = 6.022 x 1023 molecules/mol (see above to calculate moles ssRNA from mass)

* MW of a single-stranded RNA molecule = (# of bases) x (340 daltons/base)
