Answer :
Final answer:
To calculate the number of moles, multiply the concentration by the volume.
Explanation:
To determine the number of moles, you need to multiply the concentration (in moles per liter) by the volume (in liters). In this case, the given concentration is 1.5M (moles per liter) and the volume is 25mL (converted to liters by dividing by 1000). So, the number of moles can be calculated as:
1.5 mol/L x 0.025 L = 0.0375 moles
Therefore, the correct answer is option c) 0.038 moles.
