    Mass = 47.04 g

    Volume = 23.94 L

    Solution:

    The equation for given reaction is as follow,

    BaCO₃ + 2 HNO₃ → Ba (NO₃) ₂ + CO₂ + H₂O

    According to this equation,

    197.34 g (1 mole) BaCO₃ produces = 44 g (1 mole) of CO₂

    So,

    211 g of BaCO₃ will produce = X g of CO₂

    Solving for X,

    X = (211 g * 44 g) : 197.34 g

    X = 47.04 g of CO₂

    As we know,

    44 g (1 mole) CO₂ at STP occupies = 22.4 L volume

    So,

    47.04 g of CO₂ will occupy = X L of Volume

    Solving for X,

    X = (47.04 g * 22.4 L) : 44 g

    X = 23.94 L Volume
