making ice cream involves surrounding the ice cream canister with a bath of salt ice water. to get the mix of freeze at 7.00 C,how many grams of salt (NaCl;molar mass = 58) will you need to add to 3.5 kg of ice water bath? (Kf of water = 1.86C/m)
delta T = i*Kf*molality
You know delta T, i=2 (2 particles for NaCl), you know Kf, solve for molality.
Then molality = moles/kg solvent
Solve for moles.
Then moles = grams/molar mass.'
Solve for grams Nacl.
an ice cream store has 31 flavors of ice cream and 10 toppings. A regular sundae has one flavor of ice cream, one topping, and comes with or without whipped cream. How many different ice cream sundaes can be ordered?
For each pair of commodities, state which you think is the more price-elastic and gave your reasons: perfume and salt; penicillin and ice cream; automobiles and automobile tires; ice cream and chocolate ice cream.
1) For a freezing point depression experiment we had to create an ice bath and add salt to the ice. I have to answer the question, why was salting the ice necessary in order to complete the experiment and how does this apply to the …
Okay so in our class we did an ice cream lab where we use Ziploc bags to make ice cream. We made an ice cream mixture and then put it into a smaller Ziploc bag. Then we got a large Ziploc bag and placed ice in it and placed the bag …
a student puts 1.25 kg of ice in an ice cream maker with 350 g of rock salt. All the ice eventually becomes liquid water as the rock salt dissolves. Solve for the molality of the solution, then for its new freezing temperature.
