Question

What is the number of moles of glucose (C₆H₁₂O₆) in 0.500 L of a 0.40 M solution?

Answer 1

Answer:

0.20 moles

Explanation:

In order to solve this problem it is necessary to keep in mind the definition of molarity:

• Molarity = moles / liters

If we input the data given by the problem we're left with:

• 0.40 M = moles / 0.500 L

Meaning that we can proceed to calculate the number of moles:

• moles = 0.40 M * 0.500 L

• moles = 0.20 moles
