Question
Grams of protein in 237 ml buttermilk = 9 g
Therefore grams of protein in 1000 ml (1 L) buttermilk = × 1000 ml
= 37.97 g
Moles of amino acids in 37.97 g of protein =
= 0.345 mol
Mass of protein = mass of amino acids bcz protein is made up of amino acids
Here used equation to find Moles of amino acids in 37.97 g of protein is
n = n = no. of moles m = mass of sample M= molar mass
Therefore no. of molecules of amino acids = 0.345 mol × 6.022 × 1023
= 2.078 × 1023
Here used equation to find no. of molecules of amino acids is
n = n= no of moles N = no of molecules NA = Avogadro constant
no of protein molecules made from 330 amino acids = 1
therefore no of protein molecules
made from 2.078 × 1023 amino acids = × 2.078 × 1023
= 6.23 × 10 20
Answer = 6.23 × 10 20 protein molecules
made from 2.078 × 1023 amino acids = × 2.078 × 1023
= 6.23 × 10 20
Answer = 6.23 × 10 20 protein molecules
Explanation / Answer
Components in Buttermilk - Protein 0.0/2.0 points (graded) Buttermilk has 9 grams of protein per cup (237ml). If the average milk protein is 330 amino acids long, and the average amino acid has a mass of 110 g/mol, how many molecules of protein are there in one liter of buttermilk?
