          Volume of solution = 250 ml
           Concentration of carbon dioxide = 0.145%
Asked: mass of carbon dioxide

Percent by mass/ volume =  \frac{mass-of- solute}{volume-of-solution}
0.145% g/ml =  \frac{mass-of-carbon-dioxide}{250 ml}
(0.00145 g/ml) (250 ml) = mass of carbon dioxide
0.3625 g = mass of carbon dioxide
