$\boxed{\begin{array}c\boxed{\sf Element}&\boxed{\sf Mass\:in\: compound}&\boxed{\sf No\:of\:moles}&\boxed{\sf Ratio}&\boxed{\sf Simplified\:ratio}\\ \sf Sr &\sf 32.8g &\sf (32.8)/(87)=0.37&\sf (0.37)/(0.18)=2.05&\sf 2 \\ \sf Si &\sf 5.2g &\sf (5.2)/(28)=0.18 &\sf (0.18)/(0.18)=1&\sf 1\\ \sf O&\sf 11.9g &\sf (11.9)/(16)=0.74&\sf(0.74)/(0.18)=4.1 &\sf 4\end{array}}$

Empirical formula:-

$\\ \sf\longmapsto SiSr_2O_4$
