Question

A pound of coffee beans yields 50 cups of coffee (4 cups = 1 qt). How many milliliters of coffee can be obtained from 7 g of coffee beans?

Answer 1

1 pound = 453.59 g

1 qt = 946.353 ml

4 cups = 1 qt = 946.35 ml

1 cup = 236.59 ml

50 cups = 50 x 236.59 = 11829.41 ml

1 pound yields ---------------------   50 cups

453.59 g yields ------------------- 11829.41 ml

7 g yields       ------------------ ?? ml

milliliters of coffee = 11829.41 x 7 / 453.59

                              = 182.56 ml

milliliters of coffee = 182.56 ml
