1. A 2.15 L volume of KOH of an unknown concentration is mixed with 2050 mL of 0.445 M NaOH. The resulting solution is 0.985 M. Assuming the volumes are additive, find  the molarity of the first KOH solution.
2. A student prepares a 600.0 mL of 500.0 ppm of glucose solution. What volume of this solution (in millilitres) contains 0.115 g of glucose?

A patient weights 146 lbs and is to recieve a dosage of 45.0 mg per kg of body weight. the drug is supplied as solution that contains 25.0 mg of drug per mL of solution. what volume of drug should the pateint recieve?

If this reaction produced 23.0 g KCl,

23.0 g KCl, how many grams of 

O2 were produced?

When heated, KClO3 decomposes into KCl and O2.

2KClO3⟶2KCl+3O2

If this reaction produced 23.0 g KCl, how many grams of O2 were produced?

Prepare 2 liters of a 4 molal solution of MgSO4 in water. The MgSO4 is the solute and water is the solvent. Use rounded numerical atomic weights instead of exact ones with decimal values.

a) how much MgSO4 should be weighed out?

b) how many molecules of MgSO4 should be weighed out?

c)How many individual atoms of solute are present?

d) how much water should be added?

The E can be electrolyzed  after melting  to yield 4.0 grams of F and 1.6 grams of G,   neither  of which can be further decomposed by ordinary chemical means.  E combines  with water to give 1.3 grams of J per gram of E and gas L. The gas L has exactly the same    properties as the product obtained when carbon is burned in an excess of oxygen.
