QuestionExample 4: a 3.34 g sample of a hydrate has the formula $\mathrm{SrS}_{2} \mathrm{O}_{3} \cdot \times \mathrm{H}_{2} \mathrm{O}$, and contains 2.30 g of $\mathrm{SrS}_{2} \mathrm{O}_{3}$. Find the value of $x$

Studdy Solution
Find the ratio of moles of water to moles of $\mathrm{SrS}_{2} \mathrm{O}_{3}$ to determine $x$.
$$x = \frac{\text{Moles of water}}{\text{Moles of } \mathrm{SrS}_{2} \mathrm{O}_{3}}$$
Substitute the values from the previous steps to find $x$.
Solution: Assuming the molar mass $M$ of $\mathrm{SrS}_{2} \mathrm{O}_{3}$ is known, substitute the values to find $x$.
