A 0.250 g sample of the weak acid HA (molar mass = 150.0 g/mol) is dissolved in 50.0 g of water. The freezing point of the resulting solution is -0.071°C. Calculate the value of Ka for this acid. Assume molality equals molarity in this solution. (Kf for water is 1.86°C/m.)

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

since electrons are negative the answer is neagtaive

i think its 100

i hope this !

it's c (engineer's do their work with mechanical stuff not on any living being)
