Strontium does not have a pH as it is not an acid or base in itself. However, it will react with water to produce strontium hydroxide, which is a base and will produce a pH greater than 7. pH is not a measure of how strong an acid or base is, it is a measure of how acidic or basic a solution is. It depends on both how strong a dissolved acid or base is and how much is dissolved in a given volume of water.

get the volume of the chemical and the mass and divide the mass by it's volume
First, you must either find or be provided with a known mass of sodium hydroxide and a volumetric vessel. You must also know the molecular mass of sodium hydroxide, which is about 40.00. If the volume of sodium is sufficient, you can complete the preparation by determining the volume of the volume of the vessel in litres, multiply this volume by twice the molecular mass of sodium hydroxide, and dissolve the resulting mass in the known volume.
The ammonium hydroxide solution 28 % has a density of 0,9 g/cm3 at 25 oC.

(ml of Ca(OH)2)(0.0550M)= (35.00ml)(0.0550M Nitric acid) = 35ml
Phosphoric Acid dissociates to give off 3H+ ions, meaning that one mole of Phosphoric acid reacts with three mols of sodium hydroxide. Using the equation n = c x v n = 0.1 x 0.05 =0.005 mols of OH ions in the solution therefore there are 0.005/3 = 0.00167 So the volume of phosphoric acid - v = n/c v = 0.00167/0.2 v = 0.00835 l = 8.4ml of Phosphoric Acid reacts completely with Sodium hydroxide
It depends on the volume of data required by the math class. Ask your instructor.
