To solve this we use the
equation,
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
2.5 M x V1 = 1.0 M x .250 L
<span>V1 = 0.10 L or 100 mL of the 2.5 M HCl solution is needed

Answer:
Mass of CaCl₂ 136.9 g
Mass of water 223.4 g
Explanation:
The 38% by mass, means that the solution contains 38 g of CaCl₂ in 100 g of solution.
So, if the total mass of solution is 360.3 g let's make a rule of three to find out the mass of solute.
100 g _____ 38 g CaCl₂
360.3 g _____ (360.3 g . 38g)/ 100 g = 136.9 g of CaCl₂
Total mass of solution = 360.3 g → Mass of solvent + Mass of solute
360.3 g = Mass of solvent + 136.9 g
360.3 g - 136.9 g = Mass of solvent → 223.4 g
