उत्तर
π (osmotic pressure) = 8.21 atm
T = 273 + 37
T = 310 K
Hence π = CRT
where C is molar concentration.
`8.21 = w/M xx 0.082 xx 310`
where M = 180 g/mol
`w = (8.21 xx 180)/(0.082 xx 310)`
`w = 58.13` gm
∴ To prepare a solution isotonic with blood, 58.13 g of glucose per litre of solution is required.
