Given:
Volume of solution = 250 ml
Concentration of carbon dioxide = 0.145%
Asked: mass of carbon dioxide
Solution:
Percent by mass/ volume = [tex] \frac{mass-of- solute}{volume-of-solution} [/tex]
0.145% g/ml = [tex] \frac{mass-of-carbon-dioxide}{250 ml} [/tex]
(0.00145 g/ml) (250 ml) = mass of carbon dioxide
0.3625 g = mass of carbon dioxide
