What is the molality of a solution that contains 418.8 g HCl in 4.62 kg water? Select one:
O a. 2.49
Ob. 0.00249
O c. 15.3
Od.4.19e5

a. 2.49

Explanation:

Molar mass of HCl= 36.46 g

So, no. of moles=418.8/36.46=11.48

Molality= no. of moles/mass of solvent= 11.48/4.62= 2.49

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=

explanation:

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
