In this question, you are asked to make 5% Calcium chloride(CaCl2) solution. For every 1000ml of water, the weight should be 1000grams. Then for 5% solution, the CaCl2 needed would be:
5% * 500 ml * 1gram/ml= 25grams
Calcium chloride is made from 1 calcium and 2 chlorine, so the molecular mass would be (1*40) + (2*35.5)= 111 gram/moles. Then, 25 grams of CaCl2 would be: 25gram / (111 gram/moles)= 25/111 moles.
Molarity unit is mole per 1000ml of solvent. So the molarity of the solution would be: (25/111 moles) / (500ml/1000ml)= 50/111M= 0.45M
Answer:
Tertiary structure is formed by the folding of the secondary structure sheets or helices into one another. The tertiary structure of protein is the geometric shape of the protein. It usually has a polypeptide chain as a backbone, with one or more secondary structures. The tertiary structure is determined by the interactions and bonding of the amino acid side chains in the protein.
