Answer to Question #180918 in General Chemistry for ajay

Question

Determine the protein content of the following mixture, clearly showing the accuracy: Maize starch Wheat flour % Protein Weight in mixture 0.3 100 kg 12.0 22.5 kg Skim milk powder 30.0 4.31 kg 

Answer 1

Protein in Maize starch is 0.3% in 100 Kg mixture { mass of protein in maize starch = In 100 Kg mixture is 0.3 Kg }

Protein in wheat flavour us 12.0% in 22.5 Kg mixture { mass of protein in wheat flavour = In 22.5 Kg mixture is 2.7 Kg }

Protein in skim milk powder is 30.0% in 4.31 Kg mixture { mass of protein in skim milk powder = In 4.31 Kg is 1.293 Kg }

Now ,

Total protein content in the mixture = 0.3 Kg + 2.7 Kg + 1.293 Kg

= 4.293 Kg protein content in the mixture
