    Answer: 0.03798 kilograms

    Explanation:

    According to avogadro’s law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro’s number 6.023\times 10^{23} of particles.

    To calculate the moles, we use the equation:

    \text{Number of moles}=\frac{\text{Given volume}}{\text {Molar Volume}}=\frac{12L}{22.4L}=0.535moles

    1 mole of chlorine gas (Cl_2) weighs = 71 g

    Thus 0.535 moles of chlorine gas (Cl_2) will weigh = \frac{71}{1}\times 0.535=37.98g=0.03798kg            (1kg=1000g)

    Thus there are 0.03798 kilograms in 12 L of chlorine gas.
