Quizplus · Accepted Answer

To calculate the number of grams of glucose in 100 mL of a 5 M solution, we first need to convert Molarity to moles per liter:

5 M = 5 mol/L

Then, we can calculate the number of moles in 100 mL (0.1 L) of this solution:

moles = Molarity x volume = 5 mol/L x 0.1 L = 0.5 moles

Finally, we can convert moles to grams using the molecular weight of glucose (180 g/mol):

grams = moles x molecular weight = 0.5 moles x 180 g/mol = 90 grams

Therefore, the answer is C) 90.
