Solution

The correct option is C

0.005M


Explanation:

Step 1: Analyzing the given data:

The concentration of glucose in blood = 0.9gL-1

Now, the Mass of glucose in1L=0.9g

We also know that the molecular mass of Glucose =180gL-1

Step 2: Calculation of no. of moles of glucose

We can calculate No. of moles as;

n=givenmassmolarmassn=0.9g180gmol-1n=5x10-3mol

Step 3: Calculation of molarity of glucose

The Molarity of glucose is calculated as;

Molarity=no.ofmolesVolumeinlitres

M=5x10-31M=0.005M

Hence, for the given concentration of glucose, the molarity of glucose in the blood is found to be 0.005M.
