4) A typical bottle of pop holds carbon dioxide at a pressure of 5 atm. What is the concentration of carbon dioxide in th solution? 5) A stream flowing over rocks and such is exposed to the atmosphere and well aerated. What would be the nitrogen concentration in the water at 25°C? (Air pressure is 1.000 bar.)

Use the expression below to ⚫ calculate its value and report it to the proper number of significant digits (you may need to round your answer). ⚫ calculate the % error (or % relative error or % inherent error) ⚫ calculate the absolute error. (30.078±0.003) - (20.174±0.001) + (9.813±0.005) = Value: % Error: absolute error: ± % (only 1 significant digit) (only 1 significant digit)
