If the concentration of glucose (C_{6}H_{12}O_{6}) 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

The answer is the option (iii) 0.005 M


Given; Concentration of glucose- (C_{6}H_{12}O_{6}) in blood =0.9/L

Molar mass of glucose = 180 g/mol

Concentration/molar mass  =\frac{0.9}{180}

=\frac{1}{200}\; moles=0.005\; moles

Therefore the Molarity of glucose in blood is 0.005 M.
