Lysine is an amino acid that is an essential part of nutrition but which is not synthesized by the human body. what is the molar mass of lysine if 750.0 ml of a solution containing 8.60 g of lysine has an osmotic pressure of 1.918 atm? temperature = 25.0°c

Molar mass of lysine is 146.267 grams per mole.

Explanation:

Osmotic pressure(π) is given by the formula

π = cRT

where c is concentration in (Molarity).

c = no of moles per volume in litres.

R is universal gas constant = 0.0821

T is temperature in K.

Substituting values in the above equation gives

1.918 =

M = 146.267 grams per mole.

i think it is true since you can test the answer and can use observations to complete it.
