Answer:

[tex]\boxed{\text{8.91 g}}[/tex]

Explanation:

1. Calculate the moles of Sr(NO₃)₂

[tex]n = \text{366 mL} \times \dfrac{\text{0.115 mmol}}{\text{1 mL}}= \text{42.09 mmol}[/tex]

2. Calculate the mass of SrNO₃)₂

[tex]m = \text{42.09 mmol} \times \dfrac{\text{211.63 mg}}{\text{1 mol}}= \text{8910 mg} = \text{8.91 g}\\\text{The mass of strontium nitrate required is }\boxed{\textbf{8.91 g}}[/tex]
