Answer :
Final answer:
To find the volume of a 4.0 M solution of HCl made with 35.8 g of HCl, convert the mass to moles and use the molarity equation.Volume = Moles of solute / Molarity = 0.982 moles / 4.0 M = 0.2455 L = 245.5 mL.
Explanation:
Outline the steps necessary to answer the question:
- Convert the given mass of HCl to moles using the molar mass of HCl.
- Use the equation Molarity = Moles of solute / Volume of solution to find the volume of the solution.
To find the volume of a 4.0 M solution of HCl made with 35.8 g of HCl, we need to convert the mass of HCl to moles and then use the molarity equation. The molar mass of HCl is 36.46 g/mol, so the number of moles of HCl is 35.8 g / 36.46 g/mol = 0.982 moles. Using the molarity equation, we can rearrange it to solve for the volume of the solution: Volume = Moles of solute / Molarity = 0.982 moles / 4.0 M = 0.2455 L = 245.5 mL.
