Answer:
= 0.014 g of BaCO3
Explanation:
Let x = mol/L of BaCO3 that dissolve.
This will give;
x mol/L Ba2+ and x mol/L CO32-
But;
Ksp = 5.1x10^-9.
Therefore;
Ksp = 5.1 x 10^-9 = (x)(x)
Thus;
x = molar solubility
= √ (5.1 x 10^-9)
= 7.1 x 10^-5 M
Therefore;
Mass BaCO3 = 7.1 x 10^-5 M x 1 L x 197.34 g/mol
= 0.014 g
Answer:
8.65x10 7 grams of nacl
Explanation:
There are 6.02x10 23 atoms per one mol
so
8.88x 10 29 x (1/6.02 x 10 23)
Will give us mols of NaCl
to go from mols to grams we multiple mols by molar mass
so
1.48x10 6 mols of Nacl x 58.44 g/mol = 8.65x10 7 grams of nacl which can be converted to
86500 kg
