The molar mass of glucose (C₆H₁₂O₆) is approximately 180 g/mol. If 27 g of glucose is dissolved in water, what is the concentration of the solution in mol/L?
सही उत्तर: क) 0.1 M
The calculation involves dividing the number of moles of glucose (calculated from its mass) by the volume of the solution. Option 0.2 M is correct because 27 g / 180 g/mol = 0.15 mol. The other options are incorrect as they calculate different molarities.
