Answer:
Mole percent of in solution is 1.71%
Explanation:
Number of moles of a compound is the ratio of mass to molar mass of the compound.
Molar mass of = 110.98 g/mol
Molar mass of = 18.02 g/mol
Density is the ratio of mass to volume
So, mass of 60.0 mL of water =
Hence, 6.50 g of =
of
= 0.0586 moles of
60.8 g of =
of
= 3.37 moles of
So, mole percent of in solution = \frac{n_{CaCl_{2}}}{n_{total}}\times 100% =
% = 1.71%
