    Answer:

    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
