Q1: Potassium chloride has solubility 43.0 g/ 100 g water at 50oC. Will a mixture of potassium chloride (110.0 g) and water (250 g) form a saturated solution at 50oC? If so, then what mass of potassium chloride will remain undissolved?

Q2: Calculate the concentration, % m/m, of a solution containing 26.0 g solute and 726.0 g water

Q3: Calculate the molarity of a 10 % m/v solution of calcium nitrite. Use atomic weights to one place of decimals.

Q4: What volume (mL) of a 4.00 M solution must be diluted to 500 mL to yield a 5.00 x 10-3 M solution?

Q5: List the atomic weight to two places of decimals of iron, calcium, chlorine, and beryllium.
