Question

If the concentration of glucose (C6H12O6) in blood is 0.9 g L^–1, what will be the molarity of glucose in blood?
(i) 5 M
(ii) 50 M
(iii) 0.005 M
(iv) 0.5 M

Answer 1

(iii)0.0005M

molecular weight of glucose = 180 G
Given =  0.9G
Molarity= No. of moles of solute/Vol. of solvent in Litres

Answer 2

Explanation:

Concentration of glucose in blood = 0.9g/L Number of moles of glucose = 0.9180=0.005 moles

Volume of solution = 1 litre

Hence, Molarity = Number of molesVolume of solution in litres = 0.0051= 0.005M
