You can use a separating funnel. The person will go the top and the water to the bottom.
Non metal atoms got this from google btw
Density = Mass / Volume
Input the values in their respective places and then use algebra to solve for volume.
Hope that helps.
<u>Answer:</u> The molarity of HCl solution is 0.262 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

We are given:
Given mass of HCl = 0.3366 g
Molar mass of HCl = 36.5 g/mol
Volume of the solution = 35.23 mL
Putting values in above equation, we get:

Hence, the molarity of HCl solution is 0.262 M.
