Question

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 ofsoda? soda are made fizzy by the carbon dioxide (CO2)dissolved int he liquid.

Explanation / Answer

We know that the density of CO2 ,. d = 1.98 Kg / m^3 Volume of CO2 is V = 8 L = 8 * 10*-3 m^3 Density , d = mass / Volume So , mass = d * V                = 1.98 Kg / m^3 * 8 * 10^-3 m^3                 =15.84 * 10^-3 Kg                =15.84 g So the required mass = 15.84 g No .of moles , n = mass /Molar mass Molar mass of CO2 is = 12 + 2 * 16 = 44 g therefore n = 15.84 g / 44 g                 = 0.36 mol required moles = 0.36 moles
