Carbon dioxide gas has a solubility of 0.0972 g/100 g H2O at 40 degrees celsius. Expressed in parts per million, this concentration is closest to...

(1)0.972 ppm
(2)9.72 ppm
(3)97.2 ppm
(4)972 ppm

The easiest way to do these is to remember the conversion that
1 ppm = 1 mg/L
0.0972 g/100 g H2O = 0.0972/100 mL = 0.972 g/L = 972 mg/L = 972 ppm
