You can use the equation that brings together the concentration and volumen of a concentrated and diluted soultion.
The equation is:
Molarityconcentrate* Volumeconcentrate= Molaritydiluted* Volumediluted
1,00M * 0,010L = Molaritydiluted* 0,100L
Molaritydiluted = 1,00M* 0,010L/0,100L =0,1 M
So the concentration of the diluted solution is 0,1M.

A chemist dissolves 333.mg of pure nitric acid in enough water to make up 100.mL of solution. Calculate the pH of the solution. Be sure your answer has the correct number of significant digits.
A solution is prepared by dissolving 0.5892 g oxalic acid (H2C2O4) in enough water to make 100.0 mL of solution. A 10.00-mL aliquot (portion) of this solution is then diluted to a final volume of 250.0 mL. What is the final molarity of the diluted oxalic acid solution? I do not know if the answer of 0.00187 or 1.87 x 10^ -3 is correct. It is incorrect in my perspective, so i do not expect that answer, if you think...

5.00 mL of a solution containing a monoprotic acid was placed in a 100-mL volumetric flask, diluted to the mark with deionized water and mixed well. Then, 25.00 mL of this diluted acid solution was titrated with 0.08765 M NaOH. 9.23 mL of NaOH was required to reach the endpoint. a. What does the term monoprotic mean? b. Determine the molar ratio between the acid and NaOH. c. Calculate the moles of NaOH used in this titration. d. Calculate the...
(10 pts) A solution is prepared by dissolving 1.239 grams of hydrochloric acid, HCI, in enough water to make 250.0 mL of solution. A 25.00 mL sample of this solution is diluted with water to a final volume of 100.0 mL. Now, you take 10.00 mL of that solution and dilute it to 100.00 mL What is the molarity of the final solution? (HCI 36.45 g/mol)
Question 4 2.5 pts 1.00 mL of a 3.05 x 10 M solution of oleic acid is diluted with 9.00 mL of petroleum ether, forming solution A. Then 2.00 mL of solution A is diluted with 8.00 mL of petroleum ether, forming solution B. How many grams of oleic acid are 5.00 mL of solution B? (Molar mass for oleic acid = 282 g/mol) 1.19 x 10-5 g 1.72 x 10 g 4.30 x 10 g 4.30 104 g 8.60...
