For questions 3, 4, 5 use this formula:

Molarity = moles of solute/ liter of solution

 

3. How many grams of should be used to prepare 2.00 L of a 0.500 M solution?

 

4. To what volume should 5.0 g of KCl be diluted in order to prepare a 0.25 M solution?

 

5. How many grams of are needed to prepare 100 mL of a 0.10 M solution?

 

 

The molarity (  ) of a solution refers to?

A) Moles of solute/L of solution

B) Moles of solute/L of solvent

C) Moles of solute/100 mL of solution

D) grams of solute/100 mL of solution

E) grams of solute/L of solution.

A compound has an empirical formula of and a molar mass of 92.14 g/mol. Choose the molecular formula for this compound.  

Choose the appropriate definition of "molarity"

1. "The number of moles of solute dissolved in 1 liter of a solution"
2. "qualitative term for a solution containing solute at a relatively high concentration”
3. “ratio of solute-to-solution mass expressed as a percentage"
4. "The number of moles of solute dissolved in 1L of solvent"
