The molarity of a solution with 16.5 g of glucose in a 200.0 ml solution is _____ M. (Molar mass of glucose = 180.16 g/mol)
A) 0.092
B) 0.458
C) 9.158
D) 4.579
E) 0.018

Question

Quizplus · Accepted Answer

First, convert the given mass in grams of glucose to moles:

16.5 g / 180.16 g/mol = 0.09165 mol

Then, calculate the molarity by dividing moles by liters (convert 200.0 ml to liters by dividing by 1000):

0.09165 mol / 0.2 L = 0.458 M

Therefore, the answer is B.
