Matt has a stock bottle full of 6.0 M hydrochloric acid. He needs to make 500 mL of 1.5 M hydrochloric acid. Determine the amount of the stock solution and water he must use to make the required solution.

A solution made by diluting. 74 mL of a 0.981 M solution of sodium phosphate to a total volume of 250 mL. Determine the concentration of sodium ions in the solution. Provide your answer to three (3) decimal places.

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). Note: "major" chemical species are those present in concentrations greater than 10 mol/L. major species present when dissolved in water compound formula 0,0,.. iron(II) bromide FeBr, sodium nitrate NaNO3 nitrous oxide N,0

2. You are asked to make 100 ml of a 1 mM solution. How much of the 1 M concentrate do you add? How much water?

You have a 1 M stock solution of Tris-HCl. Calculate how much of it you would need to make 100 ml of a 1 mM solution of Tris-HCl. Be sure to include an unit in your answer.

In the laboratory you are asked to make a 0.170 m ammonium acetate solution using 455 grams of water. How many grams of ammonium acetate should you add? grams.

A standard solution was prepared by dissolving 0.2436 g of tin (II) chloride (SnCl2) in distilled water. The solution was diluted to a total volume of 100 mL. A 2-mL portion of this standard was then diluted to a 50-mL final volume to create the desired solution. What is the final concentration of the solution in ppm?

A 501-mL sample of a 0.184-M CaCl2  solution is left on a hot plate overnight; the following morning, the solution is 1.27 M. What volume of water evaporated from the 0.184 M CaCl2 solution? Volume =  ____mL

Can you help me with question 1?
