Soda are made fizzy by the carbon dioxide (CO2)dissolved int he liquid. An amount of carbon dioxide equal to about8.0 L of carbon can be dissolved in a 2-L bottle of soda. The molarmass of CO2 IS 44g/mol.A) How many moles of carbon dioxode are in the 2-L?(1L = 0.001M3)B) What is the mass of the carbon dioxide in the 2-L bottle of soda?
