A student placed 17.5 g of glucose (C6H12O6) in a volumetric flask, added enough water to dissolve the glucose by swirling, then carefully added additional water until the 100. mL mark on the neck of the flask was reached. The flask was then shaken until the solution was uniform. A 40.0 mL sample of this glucose solution was diluted to 0.500 L. How many grams of glucose are in 100. mL of the final solution?

A solution is made by mixing 48.2 g of alcohol into 100.0 mL of water (DH2O = 1.00 g/mL). What is the percentage of alcohol in the resulting solution?

Suppose 2.50 g of lead(II) acetate is dissolved in 300. mL of a 35.0 m M aqueous solution of ammonium sulfate. Calculate the final molarity of lead(II) cation in the solution. You can assume the volume of the solution doesn't change when the lead (II) acetate is dissolved in it. Be sure your answer has the correct number of significant digits. M x10 X Ś

You are washing glassware in a lab. The solution your 1 L beaker contains 5 mol/L NaOH in water. It is known that 1% of the mixture adheres to the walls of the beaker when the beaker is drained. Thus, if you drain the beaker, 0.01 L of the original contents of the beaker remains in the beaker. The beaker must be filled with 1 L of pure water between each rinse. The beaker is then stirred very well.  What is the composition of the contents of the beaker, in mol/L, if it is rinsed once?  How many rinses does it take to get the contents of the beaker to below 0.00005 mol/L?

Glucose (molar mass=180.16 g/mol) is a simple, soluble sugar. Glucose solutions are used to treat patients with low blood sugar. Suppose you prepare a glucose solution using the described procedure.   Step 1: Dissolve 271.8 g of glucose in enough water to make 500.0 mL of solution. Step 2: Transfer 17.7 mL of the solution to a new flask and add enough water to make 250.0 mL of dilute solution.     What is the concentration (in M) of the glucose solution at the end of the procedure?

What mass in grams (g) of C12H22O11 (sucrose) (MM=342.30 g/mol ) is needed to prepare 227.5 mL of a 0.171 M solution of sucrose in water? Give your answer rounded to two decimal places

You have 1g of lithium orotate with a molar mass of 163.03. You wish to make 100ml of 5mM lithium orotate in aqueous solution. How many grams of lithium orotate would you need?

A 7.428 g sample of KHP, a monoprotic acid, requires 49.68 mL of a KOH solution to reach the endpoint. What is the concentration of the KOH solution? Be sure your answer has the correct number of significant digits. The molar mass of KHP is 204.21 M KOH 0 x10 X g mol

One brand of laundry bleach is an aqueous solution 4.55 % NaOCl by mass. What is the molarity of this solution? Assume a density of 1.02 g/mL.  Use M as your unit with no space between your answer and the unit.

39.6 g of carbon dioxide (CO2) is dissolved in a 2 L of water.   1 L of water is added.  What is the new volume? What is the new molarity?
