Answer to Question #137693 in General Chemistry for Javier

Question

In a bottle of soda, there is 0.29 mole CO2. How many grams of CO2 are in the bottle?

Answer 1

Solution:

Number of moles of a substance in a sample is the mass in g divided by the molar mass, which gives the amount in moles.

n = m/M

molar mass of CO₂ 44.01 gram/mol

and then, calculate the mass of CO₂

m = n CO₂ × M CO₂ = 0.29mol × 44.01g/mol = 12.76 grams of CO₂

Answer: there are 12.76 grams of CO₂ in the bottle.
