Osmotic pressur of blood is 7.65 atm at 310K. An aqueous solution of glucose that will be isotonic with blood is …….wt./vol.

Options

A. 0.0541
B. 0.0354
C. 0.0453
D. 0.534

Answer

A

Explanation

`pi V = nRT` for glucose and blood, If isotonic
`pi_("glucose")=pi_("blood")`
` :. pi xx V = W/"Molar mass" xx R xx T`
Thus `7.65 xx V = W/180 xx 0.0821 xx 310`
`:. W/V=54.1g //"litre" or 5.41 %`
