Answer:
The molarity of the solution is 0.148 mol/L.
Step-by-step explanation:
Molarity of a substance in a solution is the number of moles of that substance per liter of the solution.
In this question first we have to find out the number of moles of glucose:
Number of moles = Mass in grams/molar mass of the substance.
By putting the values in the above formula:
Number of moles = 40 / 180 = 0.2223 mol
Now divide the number of moles with volume of the solution:
Molarity = 0.2223/1.5 = 0.148 mol/L.
