_3

, is sparingly soluble in water. At 25 °C its solubility–product constant is

K_{sp}=5.1\times10^{-9}

. A student adds

0.300\,\text{g}

of BaCO

_3

1.00\,\text{L}

of pure water at 25 °C, seals the container, and stirs until equilibrium is reached. (a) Calculate the molar solubility (in mol L

^{-1}

) of BaCO

_3

at 25 °C. (b) Determine the maximum mass of BaCO

_3

that can dissolve in

1.00\,\text{L}

of water at 25 °C. (c) Based on your result in part (b), calculate the mass of BaCO

_3

(in grams) that will remain undissolved in the container once equilibrium is established.
