Osmolarity of 0.3% sodium chloride solution
The correct answer is E. Assuming all solutes are impermeable, that is. All have an osmolarity of 4. To calculate osmolarity you simply multiply the number of solutes (in the this case b and c dissociate in to 4 and 2 solutes respectively) by the Molarity.

I have the following solution which is 100 ml volume
paracetamol 1 g
disoduim phosphate dihydrate 150 mg
l-cysteine HCL H2O 30 mg
soduim metabisulphate 100 mg
iwant to use mannitol to balance the osmolarity

Osmolarity is a measure of the osmotic pressure exerted by a solution around a perfect semi-permeable membrane and is compared to pure water. 1 mole of glucose dissolved in 1 litre of water has an osmolarity of 1 osmole. That means 4 om glucose has osmolarity of 4.
