The Ka is 0.0104.
To solve for the Ka, the formula is Ka = [H+][ClO-]/[HClO].
In order to determine the value of H+, the formula is H+ = 10^-pH (the pH here
is 1.80). This yields 0.015848931924611134. In the ICE table, since H+ is the same
value as ClO, then the ClO is also 0.015848931924611134. The HClO is the 0.04 -
0.015848931924611134. Substituting the values to the earlier mentioned
equation, the answer is 0.01040072606175673227903507631149 or simply, 0.0104.
<span>When a solid is dissolved, the state transitions to a liquid - a higher entropy substance than the previous solid. Therefore, the entropy of the system will increase, and, by convention, the sign of delta S will be positive.</span>

Answer: 2.06X10^-4M
Explanation: Caffeine's molar mass is 194.2 g/mole. 10 mg is 0.010 gram, so (0.01g/194.2 g/mole) = 5.15x10^-5 moles. 250 ml = 0.250 liters.
(5.15x10^-5 moles)/(0.250 liters) = 2.06x10^-4 Molar
