A specific chocolate candy contains 7.00 g of dietary fat in each 22.7-g piece. How many kilograms of dietary fat are in a box containing 2.00 lb of candy?

Question

Express your answer numerically in kilograms for it to be right

 

 

Answer 1

Conversion factors needed:

1 lb = 453.6 g

 

2.00 lb candy x 453.6g/lb = 907.2 g candy

907.2 g candy x 7.00 g dietary fat/22.7 g candy = 279.75 g dietary fat

279.75 g dietary fat x 1 kg/1000 g = 0.2798 kg dietary fat = 0.280 kg dietary fat (to 3 significant figures)
