Two glucose solutions are mixed with concentrations of 1M and 2M, respectively, in an equal volume ratio. What will the new molarity be?

A. 1.4M
B. 1.25M
C. 1.5M
D. 1.27M

Answer :

Final answer:

The new molarity of equally mixed 1M and 2M glucose solutions is 1.5M.

Therefore correct option is X

Explanation:

When two glucose solutions of different molarities (1M and 2M) are mixed in equal volume ratios, the resultant molarity can be calculated by averaging the initial molarities. Since the volumes are equal, you simply add the molarities (1M + 2M) and divide by 2. Thus, the final concentration of the mixed solution will be 1.5M.
