Amixture of table salt and ice is used to chill the contents of hand-operated ice-cream makers. what is the molality of salt in a mixture of 2.00 lb of nacl and 12.00 lb of ice if exactly half of the ice melts? assume that all the nacl dissolves in the melted ice.

First, we require the density of ice. This is 57.2 lb/ft³.

Using the following formula, we can calculate the volume of ice:

density = mass / volume
volume = 57.2 / 6 lbs

Volume = 9.53 ft³ = 270 liters

Now, the molarity of a substance is the number of moles of solute per liter of solvent. Now that we have the liters of water, we now calculate the moles of NaCl,

moles = mass / molecular weight
moles = (2 lb * 454 g / 1 lb) / (58.5)
moles = 15.5

molarity = 15.5 / 270
molarity = 0.057 molar
