1M
Sulfuric acid is typically purchased in a concentration of 18M. How many mL of the concentrated solution should be used to prepare 250mL of 0.5M sulfuric acid? How mL of water should be added?
6.94mL of sulfuric acid and 243.06 mL of water.
What is a solute?
The dissolved substance in a solution.

I have 345 mL of a 1.5M NaCl solution. If I boil the water until the volume of the solution is 250mL, what will the molarity of the solution be?
2.07M
In a solution, is there more of the solute or solvent? Why?
There is more solvent because by definition it is the major component and the solute is the substance dissolved in the solution.
What is known as the universal solvent?
Water
I have two solutions. In the first solution, 1 mole of NaCl is dissolved to make 1L of solution. In the second one, 1 mole of NaCl is added to 1L of water. Is the molarity of each solution the same? Explain your answer.
No.
How much water would need to be added to 500mL of a 2.4M KCl solution to make a 1M solution?
700mL, the final volume would be 1200mL.
