Answer :
Final answer:
The number of moles of HCl in 39.3 ml of a 1.50 m HCl solution is calculated by multiplying volume and concentration, which results in 0.05895 moles.
Explanation:
The question is asking for the moles of HCl in a specific volume of a solution with known molarity. In this case, we have the volume of the solution and its molarity. Molarity is defined as moles of solute per liter of solution. So using the formula for molarity (M = moles/liters) we can calculate the moles of HCl. Given that the molarity (M) is 1.50M and the volume(V) is 39.3 ml (or 0.0393 liters), we can use the formula as such = M * V = moles. Hence, 1.50M * 0.0393L = 0.05895 moles of HCl.
