At 25 degree Celsius, 190 grams of glucose is dissolved in 1000 grams of water. For this solution which of the following is correct ? a. M=m b. M > m c. M < m d. M is independent of m
The correct answer is c.
Calculate the molal concentration of glucose
Calculate the molar concentration of glucose
We need the density of the solution to calculate its volume.
The density will be greater than that of water, say, 1.06 g/mL.
The mass of the solution is (190 + 1000) g = 1190 g. Then
Statements a. and b. are incorrect.
The correct statement is c.
Option d. is therefore incorrect.
