What is the percentage of strontium in srcl2?

To find the percentage of strontium in strontium chloride (SrCl₂), first calculate the molar mass of SrCl₂. The molar mass of strontium (Sr) is approximately 87.62 g/mol, and that of chlorine (Cl) is about 35.45 g/mol, so SrCl₂ has a molar mass of 87.62 + (2 × 35.45) = 158.52 g/mol. The percentage of strontium is then (87.62 g/mol / 158.52 g/mol) × 100%, which is approximately 55.2%.
