a)consider the following reaction: Mg(s)+ 2HCl(aq) --> MgCl2 (aq)+H2 (g)

What minimum amount of 1.75 M HCl is necessary to produce 27.5 L of H2 at STP?

b) What is the freezing point of an aqueous solution that boils at 102.1 C?

1 answer

See above for a.
b).
delta T = Kb*molality.
solve for molality.

delta T = Kf*molality.
solve for delta T. Subtract from 0o to find freezing point.
