Question

When making homemade ice cream in a​ hand-cranked freezer, the tub containing the ice cream mix is surrounded by a brine​ (water/salt) solution. To freeze the ice cream mix rapidly so that smooth and creamy ice cream​ results, the brine solution should combine crushed ice and rock salt in a ratio of 5 to 1. A small ice cream freezer requires cups of crushed ice. How much rock salt should be mixed with the ice to create the necessary brine​ solution?

Answer 1

If the ratio of crushed ice to rock salt is 5 to 1, for every 5 cups of crushed ice, 1 cup of rock salt is needed.

To find out how much rock salt is needed for the small ice cream freezer, you can use this formula:

Rock Salt = (Crushed Ice / 5) * 1

If the small ice cream freezer requires cups of crushed ice, then:

Rock Salt = (5 cups / 5) * 1 cup

Rock Salt = 1 cup

So, you will need 1 cup of rock salt to mix with the 5 cups of crushed ice to create the necessary brine solution.
