Answer:
0.0174 mol
Explanation:
Molarity is (moles of solute)/(liters of solvent). So, to find moles you need to multiply liters by molarity.
0.0437 L × 0.400 M = 0.0174 mol
The number of moles of CH₃OH present is 0.01748 mole
From the question,
We are to determine the number of moles of CH₃OH that are in 43.7 mL of 0.400 M CH₃OH
Using the formula
Number of moles = Concentration × Volume
From the question
Concentration of CH₃OH = 0.400 M
Volume of CH₃OH = 43.7 mL = 0.0437 L
∴ Number of moles of CH₃OH present = 0.400 × 0.0437
Number of moles of CH₃OH present = 0.01748 mole
Hence, the number of moles of CH₃OH present is 0.01748 mole
