Chemistry

A sample of rainwater is observed to have a pH of 7.4. If onlyatmospheric CO2 at 390 ppm and limestone dust are present in theatmosphere to alter the pH from a neutral value, and if eachraindrop has a volume of 0.02 cm3, what mass of calcium (in ng) ispresent in each raindrop? (Do not make any simplifications.)

Note: the answer is 59 ng. some say 0.02 cm3 rain drop is equalto 0.0134 L, how did that calculation occur?
