Answer:
            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

The lowest value of the henry's law for methane gas (ch4) will be obtained with __________ as the solvent and a temperature of _
NikAS [45]

The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of  349 K.

The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of 349 K.  

Henry's law: This law states that at a constant temperature, the amount of a gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas that in equilibrium with that liquid.

Mathematically it can be written as:

          C_{g}=k\times P_{g}

So, for the methane gas , lowest value of the henry's law obtained at  349 K and with H₂O as the solvent.
