Coca-Cola has 2.2 grams of carbon dioxide gas, CO2 in each 335ml can. What is the molarity of CO2 in Coca-Cola? a. 0.14 M
b. 0.0066 mol/L
c. 0.028 mol/L
d. 0.41 mol/L

a. 0.14 M

Explanation:

Molarity is the molar concentration of a solution and can be calculated using the formula below:

Molarity (mol/L) = number of moles (lol) ÷ volume (L)

To convert the mass of CO2 to moles, we use the formula: mole = mass/molar mass.

Molar mass of CO2 = 12 + 16(2)

= 12 + 32

= 44g/mol

mole = 2.2/44

mole = 0.05mol

Volume of can = 335mL = 335/1000 = 0.335L

Molarity = n/V

Molarity = 0.05/0.335

Molarity = 0.149

Molarity = 0.14 mol/L or M
