14. A solution is prepared by dissolving 49.3g of KBr in enough
water to form 473mL of solution. Calculate the mass percent of KBr
in the solution if thedensity is 1.12 g/mL.
Which one of these salts will form a basic solution upon dissolving
in water?
A) KBr
B) KClO3
C) LiCl
D) NaNO3
E) NH4NO3
Please explain how you got the answer for my own reference, I
really appreciate it.
A solution is prepared by dissolving 171g of CdCl2 in
enough water to make 250.0 mL of solution. If the density of the
solution is 1.556 g/mL, calculate: Molarity of the solution, mole
fraction of CdCl2, and molality of the solution.
An EDTA solution was prepared by dissolving the disodium salt in
1l of water. It was standardized using 0.5063 gram of primary
standard CaCO3 and consumed 28.50 ml of the solution. The standard
solution was used to determine the hardness of a 2L sample of
mineral water, which required 35.57 ml of EDTA solution. Express
the analysis in terms of ppm CaCO3 ? Answers. 316 ppm
