Answer to Question #140399 in General Chemistry for Kali

Question

Calculate the theoretical yield of iron in your experimental sample of Total cereal based on the manufacturer’s claim that a 30-gram serving of cereal contains 100% of the recommended daily intake.

Answer 1

Based on the manufacturer’s claim is 30-gram serving of cereal contains 100% of the recommended daily intake, ie 8.7 mg

30 g contain 8.7 mg of iron

1 g contain (8.7/30) mg iron

100 g contain [(8.7/30)×100] mg iron

Hence theoretical yield of iron is

= 29 mg in every 100 g of cereal.
