A sample of 3 mol of oxygen has a volume of 22.4 L at 25 K. Find the gas’s pressure. (5 marks)

CIMETIDINE INDICATIONS

A titration is performed on a 25.0 mL sample of calcium hydroxide. A volume of 46.0 mL of a 0.15 M solution of nitric acid is used to reach to the end point. Calculate the concentration of the calcium hydroxide. (8 marks)

To prepare a 0.35 mol/L solution of calcium chloride, you add 19.4 g of CaCl2 to enough water to form 500 mL of solution.

Standard conditions are:
